Answer:
Step-by-step explanation:
The area is the sum of the areas of the two trapezoids.
Dimensions are shown on the picture.
<u>Area formula for trapezoid:</u>
<u>Total area:</u>
- A = 1/2(33 + 8)(25) + 1/2(18 + 10)(8) = 624.5 ft²
Answer:
Solution given:
BD=35ft
AC=43ft
AB=8ft
EF=33-8=25ft
AE=26ft
Now
area of right angled triangle ∆AEF
=½(EF*AE)=½(25×25)=312.5ft²
area of parallel trapezoid=½AB(BD+AC)
=½*8(35+43)=312ft²
