the length of a rectangular garden is 3 times its width. if the perimeter of the garden is 40 yards, what is the area

75 yd^2.

Step-by-step explanation:

If the width = x yards, the length will be 3x yards.

The perimeter = 2 * length + 2 * width

= 2 * 3x + 2*x = 40

6x + 2x = 40

8x = 40

x = 5

So the width is 5 and the length is 15 yards.

The area = 5 * 15 = 75 yd^2.

75

Step-by-step explanation:

x=breadth

3x=length

perimeter=2 (x+3x) = 8x

40=8x

x=5

length=15

breadth=5

area=15*5=75
