Question 954099: if the length of a rectangle is 5m longer than the width and the perimeter is 122m what is the length
Answer by algebrapro18(249) (Show Source): You can put this solution on YOUR website!
So Perimeter of a rectangle is equal to 2 times the length plus two times the width.

Lets let x = the width of the rectangle. Then we know the length is x+5 since the length of the rectangle is 5m longer than the width.

so we can plug x and x+5 into the formula for perimeter and solve for x. The euqation is:

122 = 2(x+5)+2x

I will leave you to solve this but you should get x = 28m. We need to plug this into x+5 to find the length which should give you 33m.
