## What is the formula to solve for area?

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

### Why is the area of a trapezoid b1 b2 )* H 2?

The two parallel sides of a trapezoid are its bases. If we call the longer side b1 and the shorter side b2, then the base of the parallelogram is b1 + b2. Area of a trapezoid = 1 2 (base 1 + base 2)(height). A = 1 2 h(b1 + b2) The area of a trapezoid is half its height multiplied by the sum of its two bases.

#### How can we find area of a rectangle?

The formula to find the area of a rectangle is A = l × w. Substitute 15 for ‘l’ and 4 for ‘w’ in this formula. Area of a rectangle = 15 × 4 = 60.

**How I find the area of a rectangle?**

Area of a rectangle formula To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

**Why does the formula for area of a trapezoid work?**

Dissecting the trapezoid The two parallel sides are the bases, and height, as always, is the perpendicular distance from one base to the opposite. The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height × (base1 + base2).

## What are three ways to find the area of a rectangle?

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

### What is the area of the rectangle ABCD?

The area of a rectangle ABCD is the total number of unit squares contained within it. Thus, the total area of the rectangle ABCD is 48 sq. inch. Also, using this approach, we find that the area of a rectangle is always the product of its two sides.

#### How do you find the length and area of a rectangle?

To find Length or Breadth when Area of a Rectangle is given

- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.

**What is the formula for a 1 2h b1 b2?**

The formula for a trapazoid is A=1/2h(b1+b2), express b1 in terms of A,h, and b2.

**What is the equation for the area of a trapezoid?**

A trapezoid, also known as a trapezium , is a 4-sided shape with two parallel bases that are different lengths. The formula for the area of a trapezoid is A = ½(b 1 +b 2 )h, where b 1 and b 2 are the lengths of the bases and h is the height. If you only know the side lengths of a regular trapezoid,…

## How do you calculate the perimeter of a trapezoid?

The formula for the perimeter of a trapezoid is base 1 + base 2 + side a + side b, as seen in the figure below: You need more measurements for a trapezoid, as it is a more complex form in which all sides can have a different length.

### What is the formula for the volume of a trapezoid?

Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2.

#### What is the measurement of a trapezoid?

A trapezoid has bases that are 30 and 55 centimeters in length and the non-parallel sides (or legs) are 15 and 20 centimeters.
