Answer is z=36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36
Garden area = length*width
.. = (12.5 ft)*(10 ft)
.. = 125 ft^2
Vegetable area = (1/2)*Garden area
.. = (1/2)*125 ft^2
.. = 62.5 ft^2
The area of Roberto's vegetable garden is 62.5 ft^2.
7435 divided by 5 equals 1487
