Iwill award ! ! find the areas of the trapezoids.

A = 10.5 units^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2(b1+b2) *h

b1 = 5

b2 = 2

h = 3

I found these by looking at the graph

A = 1/2(5+2) *3

A =1/2(7)3

A = 10.5 units^2

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
