The perimeter of a rectangle is 40 meters. The measure of one side of the rectangle is 12 m. What is the measure of one of the unknown side lengths?

Respuesta :

Answer:

Breadth= 8m

Step-by-step explanation:

Given:

Perimeter of rectangle= 40m

length= 12m

Proof:

Perimeter= 2*(l+b)

40= 2*(12+b)

40/2= 12+b

20-12=b

8=b

Therefore the measure of one of the unknown side is 8m
