1.	In a rectangle of perimeter one metre,one side is 5 cm longer than the other.what are the lengths of the sides?
Answer» Given that perimeter of rectangle is 1m or 100cm and let one side be x, therefore other must be = (x+5) cm Perimeter of rectangle= 2(l + b) 100= 2(x +(x + 5))50 = 2x +52x = 45x = 22.5 cm Therefore sides of rectangle are 22.5 cm and 27.5 cm

Answer»

Given that perimeter of rectangle is 1m or 100cm and let one side be x, therefore other must be = (x+5) cm

Perimeter of rectangle= 2(l + b)

100= 2(x +(x + 5))50 = 2x +52x = 45x = 22.5 cm

Therefore sides of rectangle are 22.5 cm and 27.5 cm
