## How to find the area of a trapezoid

**Common Core Standard 7.G.6**

## Area of a Trapezoid

**Area**is a measure of the number of square units found inside the trapezoid. Area is a two dimensional measure so it is always squared.

The

**height**of the trapezoid is perpendicular to the two parallel bases. One common mistake made when calculating the area of a trapezoid is to use the side length as the height. Again, the height is measured as a line perpendicular to the two parallel bases.The video below covers several of the properties of a

**trapezoid.**The area of a trapezoid may be found using the formula

**1/2h(b1+b2)**Video answers these questions

Why use the formula 1/2h(b1+b2) to find the area of a trapezoid?

What is the

**area of a trapezoid**with a height of 10 units, and sides of 12 and 16 units?What is the

**area of a trapezoid**with sides of 4,5, and 9 units?In order to solve this triangle you have to find the height of the trapezoid.
