Question

the length of a rectangle is 4 meters longer than the width. if the area is 22 square meters , find the rectangle dimension

Answer 1

Let breadth be x

• Length=x+4

We know

`\boxed{\sf Area_((Rectangle))=Length* Breadth}`

`\\ \sf\longmapsto x(x+4)=22`

`\\ \sf\longmapsto x^2+4x=22`

`\\ \sf\longmapsto x^2+4x-22=0`

• By solving

`\\ \sf\longmapsto x=-2\pm√(26)`

It doesnot have any real roots
