Answer:
14 cms
Step-by-step explanation:
If the breadth is taken as x cms, then the length is (7/5)x cms.
The perimeter of a rectangle is 2(l+b). Therefore, 2(l+b) = 48 (given)
=> 2{(7/5)x + x} = 48
=> 2(12x/5) = 48
=> 12x/5 = 24
=> x/5 = 2
=> x = 10.
=> 7x/5 =14
So the length of the rectangle is 14 cms.
