Question

Find the breath of the rectangular plot of land if it's area is 440cm square and it's length is22m and also find it's perimeter

Answer 1

area of rectangular plot= l×b
440=22×b
b=440/22
b=20m
now Perimeter = 2(l+b)
=2(22+20)
=2×42
=84m

Answer 2

The perimeter of a rectangle is "84 m".

Step-by-step explanation:

$The \ given \ values \ are:\\The \ area \ of \ a \ rectangle,A=440 \ cm^2\\The \ length \ of \ a \ rectangle,L=22 \ m\\As \ we \ know,\\Area,A=L\times B\\On \ putting \ the \ values ,we \ get\\440=22\times B\\\frac{440}{22}=B\\ B=20 \ m\\Now,\\The \ perimeter \ of \ a \ rectangle,P=2(L+B)\\P=2(22+20)\\P=2(42)\\P=84 \ m$
