Question

Find the Perimeter of the figure below, composed of a rectangle and two semicircles.

Round to the nearest tenths place.
8.

Answer 1

Perimeter of given figure = 28.56 unit (Approx.)

Explanation:

Given:

Length of long side = 8 unit

Number of long side = 2

Diameter of semi circle = 4

Number of semicircle = 2

Find:

Perimeter of given figure

Computation:

Radius of semi circle = Diameter of semi circle / 2

Radius of semi circle = 4 / 2

Radius of semi circle = 2 units

Perimeter of given figure = 2[πr] + 2[Length of long side]

Perimeter of given figure = 2[(3.14)(2)] + 2[8]

Perimeter of given figure = 2[6.28] + 16

Perimeter of given figure = 12.56 + 16

Perimeter of given figure = 28.56 unit (Approx.)
