Sample problem (perimeter)

The perimeter of a basketball court is 288 feet . If the length is 44ft larger than the width . Find the dimension of the court?

Step 1 analize We make drawing for the basketball court , P=2L +2W,

L= w+44

Step2 write the equation

P= 2L + 2W

P = 2(W +44) + 2W

Step 3 : solve

4W +88=288

W=50

Step 4 check

P= 50+50 +94 +94

P= 288 feet

Step 5.state

The dimension of the basketball court is 50 feet by 94 feet
