What is the area of the trapezoid
o 120in
o 140in
o 91in
o 182in

Step-by-step explanation:

The formula of an area of a trapezoid:

b₁, b₂ - bases

h - height

We have b₁ = 20in, b₂ = 6in and h = 7in.

Substitute:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
