Question

please find it attached i need step by step explanation

Answer 1

Answer:

Perimeter is 48cm

Step-by-step explanation:

There are two figures in this!

Let's take circle first,

Circle is having the diameter of 7 cm!

So the radius will be 3.5 cm.

Now on applying formula for circumference,

2πr

= 2 × 22÷7 × 3.5

=2 × 22 × 0.5

= 44 × 5 ÷ 10

=220 ÷ 10

= 22 cm

Now let's take rectangle which is between the circle splitted in two!

We need only outer side,

So, we need to substract the total length by the diameter of circle!

So, it will be like,

20-7=13 cm

We got 13 cm as one outer side of rectangle!

We have two sides, so it will be 2×13= 26

Now, area of the figure is 26+22=48cm.

I hope, it is clear and please mark me brainiliest !

Thank you!!!

Answer 2

Step-by-step explanation:

perimeter of two half circle = 2×(22/7)×(7/2) cm = 22 cm.

perimeter of rectangle = 2×(22+7) cm = 58 cm.

total perimeter = 22 + 58 cm = 80 cm.
