Answer:

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,

[tex]b_1=7\\\\b_2=11\\[/tex]

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

We have the formula for the area of a trapezoid:

[tex]\boxed{A=\frac{b_1+b_2}{2}\cdot h}[/tex]

Therefore, we get:

[tex]A=\frac{b_1+b_2}{2}\cdot h\\\\A=\frac{7+11}{2}\cdot h\\\\A=9h[/tex]

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

Answer:

A= 9h

Step-by-step explanation:

Here the question asks to write a formula for a given measure.

A represents the area in square feet

H represent the height and the the lengths of the base were given as 11 and 7(b1 and b2)

Area of a trapezium is height multiplied by sum of the base lenghts divided by 2

Sum of base lenght here is 18(11+7)

Height wasn't given

So the answer here is

A= 1/2×(b1+b2)×h

A=1/2×18×h

A=9h
