If the length of rectangular school hall is 4 times the width and the perimeter be 55m, then the length is 22m and the width of the school hall be 5.5m.
Given that the length of rectangular school hall is 4 times the width.
We are required to find the length and breadth of the rectangle which has the length be 4 times the width.
Perimeter of rectangle is the sum of all the length and breadth of that rectangles.
Perimeter of rectangle is given as 55m
Perimeter=2(L+B)
let the width of rectangle be x.
Length of that rectangle be 4x.
According to question,
2(x+4x)=55
2*5x=55
10x=55
x=55/10
x=5.5 m
Width be 5.5 m.
Length of rectangle be 4*5.5=22m.
Hence if the length of rectangular school hall is 4 times the width then the length is 22m and the width of the school hall be 5.5m.

Answer:
The linear equation used to find the cost to rent the shoes is
Cost to rent the shoes is $7.25.
Step-by-step explanation:
Given:
Cost of per game of bowling = $4.95
Number of games played = 5
Total money paid = $32
We need to find the cost to rent the shoes.
Solution:
Let the cost to rent the shoes be 'x'.
So we can say that;
Total money paid is equal to sum of Cost of per game of bowling multiplied by Number of games played and cost to rent the shoes.
framing in equation form we get;
Hence The linear equation used to find the cost to rent the shoes is
On solving the above equation we will find the value of 'x'.
Now we will subtract both side by 24.75 we get;
Hence Cost to rent the shoes is $7.25.
Remember, the formula of a square is . If I half x, is the new formula. Because the exponent is around the varialbe(x/2), both are squares. Therefore, the formula is .
Therefore, the new area is B: a quarter of the original.
