First, you have to find the area of the rectangular swimming pool (A1), which has 10 feet long and 6 feet wide. The area of a rectangle is:
A=A1=LxW
L=10 ft
W=6 ft
When you substitute these values into the formula, you obtain:
A1=LxW
A1=(10 ft)(6ft)
A1=60 ft²
The area of the Andrea’s backyard (A2) is 400 ft², therefore, the area of Andrea’s backyard, not including the swimming pool (A3), is:
A3=A2-A1
A3=400 ft²-60 ft²
A3=340 ft²
What is the area of Andrea’s backyard, not including the swimming pool?
The answer is: The area of Andrea’s backyard, not including the swimming pool, is 340 feet²
