Question

The perimeter of a rectangle is 92. The length is six more than 4 x the width. What is the area?

Answer 1

304

Explanation:

the perimeter of a rectangel is given by P=2(length+breadth)

let y=length and z=width

⇒y=6+4z

p=2(y+z)

⇒92=2(6+4z+z)

⇒92=12+10z

10z=80

z=8

∴y=6+4(8)=38

area=length*width

⇒area=y*z

area=8*38

area=304
