Arectangle has a perimeter of 60 units and one side of length 18 units. if it can be determined, what are the lengths, in units, of the other three sides?
a. 18,3,3
b. 18,12,12
c. 18,18,6
d. 18,21,21
e. cannot be determined from the information given

Step-by-step explanation:

Perimeter of a plane shape is the distance around the shape. The formula for determining the perimeter of a rectangle expressed as

Perimeter = 2(length + width)

The rectangle has for side. Two parallel and opposite sides are equal. There, if the length of one side of the rectangle is 18 units, it means that the length of the opposite side is also 18 units.

Since the perimeter of the rectangle is 60 units, it means that

2(18 + W) = 60

18 + W = 60/2 = 30

W = 30 - 18 = 12

Therefore, the lengths, in units, of the other three sides are 18 , 12 and 12 units
