Answer:
a) 12 ft for the length and the width
b) 7 ft as the length for each side
Step-by-step explanation:
a) Area = length x width
Since the shape is a square, that means that the length and the width have to be the same.
Because of this you have to square root 144 and you get 12 since 12x12 = 144.
b) For perimeter, this is the sum of all sides. Since a square has 4 sides and all these sides must be the same length since the shape is a square, then you have to do 28 ÷ 4 and you get 7 as your answer
