Question

The figure is made up of a semicircle and a triangle. Find the perimeter. Round your answer to the nearest hundredth.

Answer 1

Solution:

Here,

The perimeter of of the whole figure is 134.57ft.

Explanation:

Here,

The perimeter of semicircle = (22/7) x 25ft

= 78.57ft

Now,

The perimeter of triangle = 7ft + 24ft + 25ft

= 56ft

Again,

The perimeter of whole figure = perimeter of semicircle +perimeter of triangle

= 78.57ft + 56ft

= 134.57ft
