Question

The perimeters of rectangle is 100cm
and its area is 600 square centimeter.find length and breadth? ​

Answer 1

Answer:

Perimeter = 100 cm

Area = 600 cm²

Perimeter = 100 cm

2(l+b) = 100 cm

l + b = 50 cm

Area = 600 cm²

l × b = 600 cm²

By trial and error method,

30 × 20 = 600 cm²

30 + 20 = 50 cm

So, length = 30 cm, breadth = 20 cm
