Question 1069492: The length of a lacrosse field is 10 yards less than twice its​ width, and the perimeter is 400 yards. The defensive area of the field is Fraction 7 Over 25
of the total field area. Find the defensive area of the lacrosse field.
The defensive area of the lacrosse field is how many square yards?
A man has a rectangular garden. One length of the garden lies along a patio wall.​ However, the rest of the garden is enclosed by 24 feet of fencing. If the length of the garden is twice its​ width, what is the area of the​ garden?

width=x
length is 2x-10
half perimeter is length=width=200 yds
x+2x-10=200
3x=210
x=70 yds width
2x-10=130 yds length
area is 130*70=9100 sq yd
7/25*(9100)=2548 sq yds
-----------------------------
width=x
length=2x
perimeter=4x, two widths and one length=24 feet
x=6 feet
width is 6 ft.
length is 12 ft.
It has an area of 72 ft^2
