Question

The length of a rectangle is 18 cm and it's breadth is 10 cm when the length is increased to 25cm what will be the breadth of the rectangle if the area remains same.

Answer 1

Answer:

3

Step-by-step explanation:

Area of 1st case = 2×(l+ b)

= 56cm sq.

Area of 2nd case where L =25

56= 2( L+B )

28= L+B

28-L =B

B=28-25=3
