PLEASE HELP!!! The question is above^

Answer 1

Answer:

C

Step-by-step 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 = $\sqrt{(5-0)^2+(0-5)^2}$

    = $\sqrt{5^2+(-5)^2}$

    = $\sqrt{25+25}$ = $\sqrt{50}$

Hence

Perimeter = 4EF = 4 × $\sqrt{50}$ ≈ 28.3 → C
