Rafael is fertilizing his garden. The garden is in the shape of a rectangle. Its length is 16 feet and its width is 13 feet. Suppose each bag of fertilizer covers 26 square feet. How many bags will he need to cover the garden?
step 1
Find the area of the garden
Remember that the area of a rectangle is equal to
A=L*W
we have
L=16 ft
W=13 ft
substitute
A=16*13
A=208 ft^2
step 2
we know that
each bag of fertilizer covers 26 square feet
so
Applying proportion
1/26=x/208
solve for x
x ----> number of bags
x=(1/26)*208
x=8 bags
therefore
