Question

Dogwood Park is 30 yards long by 20 yards wide. Kylie is making plans to double the area by adding a strip at one end and another strip the

same size as the width at the other end. Find the width of the strip.
a. 10 yards
b. 60 yards
c. 20 yards
d. 30 yards

Answer 1

the original area is 20*30 = 600 square yards



600*2 = 1200 square yards

1200=(20+x)(30+x)

x=10

So 10 strips
