Question

find perimeter of
lus
the following
shopes
- 17m​

Answer 1

Answer:

Perimeter of the figure is = 44 + 26.69 = 70.69cm ans.

Step-by-step explanation:

This figure can be splitted into two parts

• Rectangle
• Semi-circle

Perimeter of this figure = perimeter of the rectangle + perimeter of the semi-circle

So,

We know that,

Perimeter of the rectangle = 2(l + b)

Where,

l = 17cn

b = 5cm

Therefore,

Perimeter = 2(17 + 5)

= 2(22)

= 44cm.

Now,

Perimeter of the semi-circle = πr

Where,

radius will be = 17/2cm

Therefore,

Perimeter = 3.14 × 17/2 = 26.69cm

Hence,

Perimeter of the figure is = 44 + 26.69 = 70.69cm ans.
