A rectangle is 14 cm long and 10 cm wide. If the length is reduced by x cms and its width is increased also by x cms so as to make it a square then its area changes by :
given len=14,breadth=10 len decreases by x,and length increases by x so it makes square means perimeter of a rectangle=48 is same perimeter of a square =48 side of a square=12 area = 144 ans is b
a
ReplyDelete14-x=10+x
x=2&area of rectangle is 140
