Question

Find the perimeter of each fig figure

Answer 1

Answer:

perimeter of rectangle =2(l+b)=2*18=36cm and perimeter of semicircle=2*22/7*6=37.714

Answer 2

Step-by-step explanation:

First start with the easy shapes. i.e. rectangle.

Perimeter of rectangle = 2(l+b)

=2(12+6)

=2×18

=36m

Perimeter of semicircle=

$\pi \times r \\ = \frac{22}{7} \times \frac{1}{2} \times 6$

Here radius = 1÷2 × 6

=66÷7

=9.42

Therefore perimeter of entire shape= 9.42+36=45.42
