-
- c 82%area of square=x^2
inc length=1.4x
Inc breadth=1.3x
Area of rec=l×b= 1.82x^2
Inc in area= 1.82x^2 -x^2 = 82% - 10 years agoHelpfull: Yes(0) No(0)
- suppose a=1 then area of square is 1
area of rec =1.4 * 1.3 =1.82
area of rec - area of square =1.82-1=0.82
0.82*100=82% - 5 years agoHelpfull: Yes(0) No(0)
