Question

the perimeter of a rectangle is130. If the breath of the rectangle is 30 , find its length .also find the area of the rectangle

Answer 1

perimeter of rectangle- 130
breath of rectangle- 30
ATQ
Perimeter=2( l+b)
= 130=2l+60
=130-60=2l
=70=2l
=70/2=l
35=l
here, length is 35.
AREA OF RECTANGLE = Length* Breath
=35*30
1050
Answer is 1050sq cm

Answer 2

The Area is "1050 cm²" and the length is "35 cm".

Step-by-step explanation:

$The \ given \ values \ are:\\The \ perimeter \ of \ rectangle, P=130 \ cm\\The \ breadth,B=30 \ cm\\The \ length \ and \ the \ area=?\\As \ we \ know,\\Perimeter,P=2(L+B)\\On \ putting \ the \ values \ in \ above \ formula,we \ get\\130=2(L+30)\\55=L+30\\L=55-30\\L=35 \ cm\\Now,\\Area = L\times B\\Area=35\times 30\\Area=1050 \ cm^2$
