Question

Find the perimeter of the rectangle whose length is 70cm and breadth is 30 cm

Answer 1

Length of rectangle, l = 70cm

breadth, b = 30cm

Perimeter = 2(l+b) = 2(70+30) = 2×100 = 200 cm

Hence, perimeter of the rectangle is 200cm

Answer 2

Perimeter =2(l+b)
Perimeter = 2(70+30)
=2(100)
=200
Then,
Perimeter= 200cm
