Write a formula for the given measure. Let A represent the area in square feet, and h represent the height in feet. Identify which variable depends on which in the formula. the area of a trapezoid with base lengths of 7 feet and 11 feet A=

So, the area of a trapezoid is A=9h  in square feet.

Step-by-step explanation:

We know that a  h represent the height in feet. We have that the  base lengths of 7 feet and 11 feet. So,

We calculate the  area in square feet, where A  represent the area.  

We have the formula for the area of a trapezoid:

Therefore, we get:

So, the area of a trapezoid is A=9h  in square feet.

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
