Question

What’s the area ? 50 points

Answer 1

• The area of the figure is 325.17 ft²

===============================

The area of the given shape can be found as a sum of three simpler shapes:

• Triangle, rectangle and semi-circle.

The semi-circle has the radius of 9 ft, its area is:

• A = πr²/2 = 3.14*9²/2 = 127.17 ft²

The rectangle has dimensions of 9 ft and 26 - 9 = 17 ft, its area:

• A = lw = 9*17 = 153 ft²

The triangle has bas of 9 ft and height 26 - 9 - 7 = 10 ft, its area is:

• A = bh/2 = 9*10/2 = 45 ft²

Area of the shape is:

• A = 127.17 + 153 + 45 = 325.17 ft²
