1 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?
Answer first you have to make it a square by subtracting 2cms from the length and adding 2cms to the width. That will make it equal to 12cm. The area for the rectangle was 140cm then it increased by 4 because 12cm * 12cm is 144cm.So x = 2 and the area increases by four.
