Answer:
length is 44cm and breadth is 33cm.
Step-by-step explanation:
Let length be 4x and breadth be 3x.
2*(4x + 3x) = 154cm. ( perimeter is twice the sum of length and breadth ).
=> 14x = 154
=> x = 11
Therefore, length is 44cm and breadth is 33cm.

Answer:
The Length is 44 cm and Breadth is 33 cm.
Step-by-step explanation:
Given :
Ratio = 4 : 3
Perimeter = 154 cm
To find :
Length and Breadth
Solution :
Let the -
- Length = 4y
- Breadth = 3y
★
154 = 2(4y + 3y)
154 = 8y + 6y
154 = 14y
y = 154/14
y = 11
★ Length -
4(11)
44 cm
★ Breadth -
3(11)
33 cm
The Length is 44 cm and Breadth is 33 cm.
