Question

the length of rectangle twice the width of it. If perimeter of rectangle is 42 meters,find the area of rectangle

Answer 1

let the breath be x then the length will be 2 x
therefore 6x=42 :;x=7
length=14
breadth=7
thus area =14×7=98

Answer 2

Let width be x
And length be 2x
So, 2(x+2x)=42
2(3x)=42
6x=42
X=42/6
X=7
So, width is 7
And length be (2x7)=14
Therefore, area =length x width
=7x14 m square
=98m square
