The length of a rectangular garden is 30 yards more than the width. The perimeter is 300 yards. Find the length and width. L= yards, W=yards

Answer 1

• L = 90 yards
• W = 60 yards

Explanation:

The formula for the perimeter of a rectangle is ...

P = 2(L+W)

If the length is 30 yards more than the width, we can use L = W+30 and substitute known values into the above formula:

300 = 2((W+30) +W)

150 = 2W +30 . . . . . divide by 2 and collect terms

120 = 2W . . . . . . . . . subtract 30

60 = W . . . . . . . . . . . divide by 2

60+30 = L = 90

The length is 90 yards; the width is 60 yards.
