"From the given details, we can use the ration of the length of the breadth of the rectangle is 5:3. The perimeter of the rectangle is 144m. We can take 5:3 as 5x : 3x. The perimeter is 144.
It is a known fact that 2(l + b)=144.
2(5x + 3x)=144
8x=72
The value of x is 9. The length is l*b which is 45cm.

Hey mate !!
Q) If the ratio of the length to the breadth of a rectangle be 5:3 and its perimeter is 144 m, find the length of the rectangle .
solution:-
let the length and breadth be 5x and 3x respectively,
A/Q
2(l+b) = perimeter
2(5x+3x) = 144
2 × 8x = 144
16 x = 144
x = 9
therefore , length = 5x I.e., 5 ×9 =45 Answer!!
