Hi there!
Since the scale is 1 in = 4 ft, we divide both the length and width by 4 to get the new length and width with the scale factor applied.
16 / 4 = 4
12 / 4 = 3
So, the
length = 4
width = 3
Hope this helps!
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 = 
= 
=
= 
Hence
Perimeter = 4EF = 4 ×
≈ 28.3 → C
