Here is u answer if it helps u please mark me as brainlist
Given :
Perimeter of rectangle = 240 cm
Assume length as = x + 10
Breadth as =x
Perimeter of rectangle = 2(l+b)
240 = 2( x +10 + x)
240/2 = (2x + 10)
120 = 2x + 10
120-10 = 2x
110 = 2x
110/2 = x
55 = x
Therefore: length = x +10
55 + 10 = 65 cm
Breadth = x
= 55 cm
