francisco is building a window seat below a bay window in the shape of an isosceles trapezoid. His blueprint for the window seat is shown 5ft 4ft 1ft 1ft

Answer 1

The area of an isosceles trapezoid is given by the formula:

Area = (1/2) * (sum of the lengths of the parallel sides) * (height)

In this case, the blueprint shows that the lengths of the parallel sides are 5ft and 4ft, and the height is 1ft.

Therefore, the area of Francisco's window seat would be:

Area = (1/2) * (5ft + 4ft) * 1ft
Area = (1/2) * 9ft * 1ft
Area = 4.5ft²

So, the area of Francisco's window seat is 4.5 square feet.
