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

Answer:

The perimeter is 55.68 cm.

Step-by-step 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:

$2(3.14\times6)+2(9)$

= $2(18.84)+18$

= $37.68+18$

= 55.68 cm

Therefore, the perimeter is 55.68 cm.
