Answer:
Part a) The width of parking lot is 87m.
Part b) The length of rectangular pool is 94 m
Explanation:
a) The area of parking lot Area= 8439 m^2
Length of Parking Lot = Length = 97 m
Width of Parking Lot = Width= ?
Area of rectangle = Length * Width
Putting the values,and finding width,
8439 = 97 * Width
=> Width = 8439/97
=> Width = 87 m
So, The width of parking lot is 87m.
b) Perimeter of rectangular pool = Perimeter= 344 m
Width of rectangular pool = Width = 78 m
Length of rectangular pool = Length = ?
The formula for perimeter is:
Perimeter = 2*(Length + Width)
Putting values in the formula:
344 = 2*(Length + 78)
344/2 = Length + 78
172 = Length + 78
=> Length = 172 - 78
Length = 94 m
So, the length of rectangular pool is 94 m.
