The expression . 40 + 20π and 10 + 10 + 10π + 10 + 10 + 10π gives the correct value of the perimeter is 102.8 .

We have to determine, the perimeter of the given shape in the question.

According to the question,

The squares have a side length of 10 and 1 square side is the radius of the half-circles.

There are two half-circles,

To find the circumference for one full circle:

$C = 2\pi r$

Where radius = 10

$C = 2\times 3.14 \times 10\\\\C = 62.8$

The circumference of the circles is 62.8.

To find the perimeter of the exposed squares with side length 10.

There are 4 exposed sides, which equals one square.

Therefore, perimeter p is given as,

$P = 10+10+10+10\\\\P = 40$

On adding the perimeter of the circle and the square together:

P = 62.8+ 40 = 102.8

Check all the statement which give perimeter of the shape,

$40+20\pi = 40+ 20\times3.14 = 102.8\\\\20\pi = 20 \times 3.14 = 62.8\\\\120+20\times \pi = 120+20\times3.14= 182.8\\\\300 + 100\times\pi = 300+100\times3.14 = 614\\ \\10+10+10\times\pi +10+10+10\times\pi = 40+ 20\times3.14 = 102.8$

Hence, The expression . 40 + 20π and 10 + 10 + 10π + 10 + 10 + 10π gives the correct value of the perimeter is 102.8 .

1 and 5

Step-by-step explanation:

The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:

$C=2\pi r$

Insert the radius:

$r=10\\C=2\pi *10$

Simplify pi:

C=2*3.14*10

Simplify multiplication:

$C=6.28*10\\C=62.8$

The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:

$P=10+10+10+10\\P=10+10+20\\P=10+30\\P=40$

Add the perimeter of the circle and the square together:

P=62.8+40=102.8

Now see which of the options gives you the perimeter:

1. $40+20\pi =102.8$ ****

2. unavailable

3. $120+20\pi =182.8$

4. $300+100\pi =614.2$

5. $10+10+10\pi +10+10+10\pi =102.8$ ****

Finito.
