Question

Length of of a rectangle whose perimeter is 600 cm and breath is 100 cm then what is length

Answer 1

Answer:

We know that for a rectangle, perimeter = 2(L+B) = 2L + 2B.

Given, perimeter = 100 and length = 30, putting the values:-

2(30) + 2(b) = 100 [where b = breadth].

OR b = 20cm.

And Area = L x B = 30 x 20 = 600sq.cm.
