The table below shows the relationships between the area and perimeter of four squares.
Squares
Area, A
(square units) Perimeter, P
(units)
16 16
25 20
36 24
49 28
Which equation can be used to find A, the area of a square that has a perimeter of P units?
Responses
A A = P × 4A = P × 4
B A= (P + 4)A = ( P + 4)
C A = (P ÷ 4) × (P ÷ 4)A = ( P ÷ 4) × ( P ÷ 4)
D A= (P × 4) ÷ 4
