Question

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse?

24.5 square feet
59.5 square feet
70 square feet
147 square feet

Answer 1

Area of this figure = Area of square + area of triangle

A(square) = 7^2 = 49ft2
A(triangle) = (7x3) : 2 = 10.5ft2

So, the area of this doghouse is : 49 + 10.5 = 59.5ft2.
