8. 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?

9. Step 1 analize
 We make drawing for the basketball court , P=2L +2W,
 L= w+44

10. Step2 write the equation
P= 2L + 2W
P = 2(W +44) + 2W

11. Step 3 : solve
4W +88=288
W=50

12. Step 4 check
P= 50+50 +94 +94
P= 288 feet

13. Step 5.state
The dimension
of the basketball
court is 50 feet by
94 feet

15. Mixture problem
The price of brand A rice is
