Answer:
A. 1 inch by 5 inches
B. 3 inches by 3 inches
Step-by-step explanation:
The perimeter of a rectangle is the sum of the sides of the rectangle. The perimeter of a rectangle can be represented mathematically as
perimeter of a rectangle = 2l + 2w
where
l = length
w = width
perimeter = 12 inches
perimeter of a rectangle = 2l + 2w
12 = 2(l + w)
divide both sides by 2
l + w = 12/2
l + w = 6
Base on the option the dimension can only be 1 inches by 5 inches because the sum can give 6.
Square
The perimeter of the square is 12 inches.
perimeter of a square = 4l
where
l = length
12 = 4l
divide both sides by 4
l = 12/4
l = 3 inches
The length should be 3 inches by 3 inches.
