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.

Answer:
x = 3.75 cm
Step-by-step explanation:
If we assume ΔABC ~ ΔXYZ, then ...
YZ/BC = YX/BA . . . . . . corresponding sides are proportional
x/15 = 3/12 . . . . . . . . . . . fill in given values
x = 15(3/12) = 15/4 . . . . . multiply by 15
x = 3.75 . . . cm
