Answer:

Step-by-step explanation:
We are given the statement,
'The square of y decreased by the quotient of 28 and 7'.
i.e. Subtracting the quotient
= 4 from
.
i.e. 
Hence, the expression which represents the given statement is
.
Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.

Subtract 60 from both sides and factor the quadratic to solve for w.

Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
