Question

The Perimeter of a rectangle is 140 cm. If the breadth is 30 cm, find the length, Also find the area

Answer 1

Answer:

perimeter = 140cm.

if, breadth is = 30cm.

Let, the length be x.

(A.T.Q) 2(x + 30) = 140

=> 2x + 60 = 140

=> 2x = 140 - 60

=> 2x = 80

=> x = 80/2

=> x = 40

so, the length is 40cm.

Then, the area is

= 40 × 30

= 1200 cm²
