Question

Find the perimeter of rectangle whose area=10000m,length=100m

Answer 1

Breadth=100
perimeter= 2. 200
perimeter= 400m

Answer 2

The perimeter is "400 m" and the breadth is "100 m".

Step-by-step explanation:

$The \ given \ values \ are:\\The \ area \ of \ a \ rectangle,A=10000 \ cm^2\\The \ length,L=100 \ m\\As \ we \ know,\\Area \ of \ a \ rectangle=L\times B\\On \ putting \ the \ values ,we \ get\\10000=100\times B\\\frac{10000}{100}=B\\ B=100 \ m\\Now,\\The \ perimeter \ of \ a \ rectangle,P=2(L+B)\\On \ putting \ the \ values \ in \ the \ above \ formula,we \ get\\P=2(100+100)\\P=2(200)\\P=400 \ m$
