Answer:
Length = 24 cm
and, Width = 8 cm
Explanation:
It is given that,
Length = 3 × (width)
⇒ L = 3W → (1)
Also, since perimeter = 64 cm
And perimeter of rectangular garden = 2(L + W) = 64
From equation (1)
2(3W + W) = 64
2 × 4W = 64
⇒ 8W = 64
⇒ W = 8 cm
Putting value in equation (1)
L = 3 × 8 = 24 cm
thus, Length = 24 cm
and, Width = 8 cm
