Question

Find the perimeter of the shape

Answer 1

Step-by-step explanation:

Perimeter = 3( 8.1) +

$\pi \times (81 \div 2)$

solve it

this will be your

answer

Answer 2

Step-by-step explanation:

Perimeter of semi circle = πr + 2r

Here, we do not need to include 2r because it is part of the square which in side the entire shape.

Radius of semi circle = half of side of square = 4.05

Therefore, perimeter of shape = Sum of 3 sides + πr

Perimeter = (3*8.1) + π(4.05)

= 24.3 + 4.05π
