Question

Pls help i don’t understand guys. i put the image down thank you sm if anyone decides to help hahahah ik it’s just perimeter but i struggle when it comes to math

Answer 1

21.41

Explanation:

The 1/2 circle:

c = 1/2 (2
`\pi`r) I am going to use 3.14 for
`\pi`

c = 1/2(2)(3.14)(2.5) The diameter is 5 and the radius is 1/2 of that or 2.5

c = 1/2(15.7)

c = 7.58

Triangle:

We need to find the hypotenuse of the triangle. The legs are 1 and 1. The measurement of 1 leg is given as 1. The other leg is 1 because I see the diameter of the circle is 5 (3 + 1 + 1), so I can infer that the other leg is 1.

`a^(2)` +
`b^(2)` =
`c^(2)`

`1^(2)` +
`1^(2)` =
`c^(2)`

1 + 1 =
`c^(2)`

2 =
`c^(2)`

`√(2)` =
`\sqrt{c^(2) }`

`√(2)` = c

The length of the diagonals on both sides of the figure is
`√(2)`

2
`√(2)` is the length of the triangle part. We can round this to 2.83

Rectangle:

4 + 3 + 4 = 11

The rectangle part is 11

Adding it all together:

7.58 + 2.83 + 11 = 21.41

This is not an exact answer. I rounded the answer to 2 decimal places.
