I need to create my own area word problem for extra credit (algebra 1)

Bob has a garden

the area is 75 square feet

the legnth is 3 times the width

solve

75=lw

l=3w

subsitute

75=3w times w=3w^2

75=3w^2

sdivide by 3

25=w^2

square root

5=width

subsitute

3w=l

3 times 5=l

l=15

width=5

legnth=15
