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