Question

the perimeter of the parallelogram is 102 feet. Find m. Write your answer as a decimal or mixed number.

Answer 1

m = 13.5

Explanation:

The perimeter of a parallelogram is calculated by using the following formula:

P = 2(a+b) (a: base, b: side)

Here, the base and side are represented with m and 3m.

2(m+3m) = 102 first find the sum of side and base then multiply it by 2

2*4m = 102 multiply

8m = 102 divide both sides by 8

m = 13.5
