  • The length and width of a rectangle are in the ratio 3:5.
Question 1:
The length and width of a rectangle are in the ratio 3:5. If its perimeter is 48 cm, find its length and width.
A. 9, 15
Feedback From the given ratio,
length = 3x and width = 5x
Perimeter = 48
2(l+w) = 48
2(3x + 5x) = 48
8x = 24
x = 3
Therefore,
Length = 3(3) = 9 cm
Width = 5(3) = 15 cm.
B. 6, 18
C. 5 14
D. 8, 20
