# How do you find the area of a isosceles trapezoid?

## How do you find the area of a isosceles trapezoid?

The formula to calculate the area of an isosceles trapezoid is Area = (sum of parallel sides ÷ 2) × height.

How do you find the height of a trapezoid with the area and bases?

Write A=h(b1+b2)/2, where A represents the trapezoid’s area, b1 represents one of the base lengths, b2 represents the other base length and h represents the height. Rearrange the equation to get h alone. Multiply both sides of the equation by 2 to get. 2A=h(b1+b2).

How do you find the perimeter of an isosceles trapezoid?

The perimeter is the sum of the outer edge of the shape, so you just need to add the lengths of the sides. Because this is an isosceles trapezoid, the legs are the same length, so you can use 2c in the formula since both the legs are of equal length. Step 2: Substitute known values for variables: P = 5 + 10 + 2(7)

### How is the trapezoid related to the isosceles trapezoid?

A trapezoid is a cyclic quadrilateral (that is, can fit inside a circle) with one pair of parallel sides. An isosceles trapezoid has one pair of parallel sides and another, different pair of congruent sides. They look like this: The trapezoid has one line of symmetry – the cyan line.

How to calculate the area of an isosceles trapezoid?

a, b and c are the sides of the trapezoid. The Area of isosceles trapezoid formula is. \$\\large Area\\;of\\;Isosceles\\;Trapeziod=h\\left [\\frac{a+b}{2}\\right]\$ Where, a and b are the parallel sides of trapezoid.

What is the trapezoid formula for area?

Area of a trapezoid formula. The formula for the area of a trapezoid is (base 1 + base 2) / 2 x height, as seen in the figure below: The calculation essentially relies on the fact a trapezoid’s area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area.

## How to find the perimeter of a trapezoid?

You can notice that for a trapezoid with a = b (and hence c = d = h), the formula gets simplified to A = a * h, which is exactly the formula for the area of a rectangle. How to find the perimeter of a trapezoid?

How long are the legs of a trapezoid?

Question 1: A trapezoid has legs 8 cm each in length. Its bases are 10 cm and 15 cm respectively. Calculate its perimeter.
