the length of a rectangle is 18 cm and its breadth is 10 cm . when the length is increased to 25 cm , what will be the breadth of the rectangle if the area remains the same ?
solution let the breadth be b . then , ⇒ 25 b = 18 × 10 ⇒ b = ( 18 x 10 / 25 ) cm = 7.2 cm answer c
divide(multiply(18, 10), 25)
