A rectangle has a perimeter of 72 millimeters and a width of 8 millimeters. What is the length of this rectangle?
Enter your answer in the box.
____mm

Respuesta :

Answer:

length = 28 mm

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

• P = 2(length + width )

given P = 72 , then

2(length + width) = 72 ( divide both sides by 2 )

length + width = 36 ( substitute width = 8 )

length + 8 = 36 ( subtract 8 from both sides )

length = 28 mm
