Question

Francisco is building a window seat below a bay in the shape of an isosceies trapezoid. 5ft by 4ft by 1ft by 1ft what is the area?

Answer 1

As given, the dimensions of the isosceles trapezoid are =

5 ft = this is the base 1

4 ft = this is the base 2.

1 ft by 1 ft = this is the height

Here, base 1 and base 2 are the parallel sides of the trapezoid

Area = {(sum of base 1 and 2)(height)}/2

=
`((5+4)*1)/(2)`

=
`(9)/(2)`

Area = 4.5 square feet.
