Question

HELP PLEASE I NEED ANSWER ASAP!

Answer 1

111.4556

Explanation:

Perimeter = 18 + 25 + 18√2 + 43

Perimeter = 86 + 18√2

Perimeter = 86 + 18(1.4142)

Perimeter = 86 + 25.4556

Perimeter = 111.4556

Answer 2

86+18
`√(2)`

Explanation:

Use the properties of 45-45-90 triangles to get a side length of 18 for the 2 legs of the isosceles triangle. Then add 43+18, which is the shorter length of the rectangle, +25, which is the longer edge, +18
`√(2)`. The answer is now 86+18
`√(2)`.
