PLEASE HELP!!!
The question is above^

Answer 1

C

Explanation:

Since the figure is a square with all 4 sides equal, then calculate the length of EF and multiply by 4 for the perimeter.

Calculate EF using the distance formula

EF = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = E(0, 5) and (x₂, y₂ ) = F(5, 0)

EF =
`√((5-0)^2+(0-5)^2)`

=
`√(5^2+(-5)^2)`

=
`√(25+25)` =
`√(50)`

Hence

Perimeter = 4EF = 4 ×
`√(50)` ≈ 28.3 → C
