Step-by-step explanation:
let the breadth be X
length is three time to breadth 3x
perimeter = 2 (l+b) = 24 cm
= (3x+X)^2 = 24 cm
= 2(3x+X)^2 = 24 cm
= 6x+2x = 24 cm
= 8x = 24 cm
8x= 24 cm
X= 24/8. ( Divided by 8 to 24)
X = 3 cm
- Breadth = 3 cm
- length = 3×3 = 9 cm
- thanks dear friend
- I hope you help
