Answer: Area = 4000ft^2
Step-by-step explanation: The area bounded by the fence = (72+4+4)(42+4+4) = 4000ft^2
Answer:
area of the rectangular yard = 72 × 42 = 3024 ft²
area bounded by the fence = 34 × 64 = 2176 ft²
area of walk = 848 ft²
Step-by-step explanation:
The rectangular yard has a dimension of 42 ft by 72 ft.
The area of the rectangular yard = Length × width
L = 72 ft
W = 42 ft
area of the rectangular yard = 72 × 42 = 3024 ft²
The rectangular yard is surrounded by a fence and a walkway is also inside the fence . This means reduce 4 ft for all sides of the rectangular yard to get the area of the walkway. This means reduce 8 ft to the length and width of the rectangular yard.
Length of fence = 72 - 8 = 64 ft
width of fence = 42 - 8 = 34 ft
area inside the walkway = 64 × 34 = 2176 ft²
area of walk = 3024 - 2176
area of walk = 848 ft²
