Answer:
a) 484 square feet of ground will be needed to cover with gravel.
b) 14 feet is the length of one of the walls in his room
Step-by-step explanation:
Area of the square = [tex]A=(Side)^2[/tex]
a) Length of the side of the square driveway ,s= 22 feet
Area of ground covered by gravel be A.
Area enclosed by square driveway is equal to area of ground covered by gravel.
[tex]A = s^2[/tex]
Area of square driveway = A= [tex]s^2=(22 ft)^2=484 ft^2[/tex]
484 square feet of ground will be needed to cover with gravel.
b) Area of the square carpet ,A= [tex]196 ft^2[/tex]
Area of the square carpet is equal to the area square bedroom
Length of the square carpet = s
Length of the carpet = Length of the room of Micheal's bedroom
[tex]A = s^2[/tex]
[tex]196 ft^2=s^2[/tex]
s = ±14 ft
Ignoring the negative value , we get :
s = 14 ft
14 feet is the length of one of the walls in his room.
