Question

the length of a rectangle is 3 times its breadth of the area if the area of the rectangle is 1875 square cm find its perimeter

Answer 1

Let the breadth be x cm
Therefore length =3x
Area=1875cm sq
According to the question,
3x×x=1875
x^2=1875/3
x^2=625
x=25cm
Now, length =25×3=75cm
Breadth =25
Perimeter of rectangle =2(l+b)=2(25+75)
2(100) =200cm.ans

Answer 2

Hello dear,
Area =l * b
=>1875=3x*x
=>3x²=1875
=>X²=625
=>X=25

Perimeter =(3x+3x+x+x)
=>(3*25+3*25+25+25)
=>(75+75+25+25)
=>(150+50)
=>200cm

I hope you understand very well dear
:-)
