Answer 1

Area of triangle, ECD
Area, A= 60 square inches
Base, b= 12in
Height, h=?

Note that Area of a triangle = 1/2×b×h
Substitute the values: 60 = 1/2×12×h
60 = 6h
h = 10in

The height is 10in.



Coincidentally, the height of the triangle is also the side of the square.
So side of square, L = 10in

Area of a square = L^2 or Side × Side
Area = 10 × 10
Area = 100 square inches.



The area of the trapezoid = area of square + area of triangle
The are of trapezoid = 100 + 60 inches squared = 160inches squared.
