Question

Study the dimensions of the shape. Find it’s perimeter. Use 3.14 for pi.

Answer 1

It’s just a square that’s displaced. 12*9=108

Answer 2

The perimeter is 55.68 cm.

Explanation:

We have 2 sides as 9 cm.

We have the diameter as 12 cm. So, radius = 6 cm

Circumference of complete circle is =
`2\pi r` So, circumference of half circle will be
`\pi r`

Now the perimeter of the whole figure will be given as:

`2(3.14*6)+2(9)`

=
`2(18.84)+18`

=
`37.68+18`

= 55.68 cm

Therefore, the perimeter is 55.68 cm.
