Question

The area of rectangle is 36 cm2 and breadth is one fourth of the length.Find length and breadth of rectangle.​

Answer 1

• Let breadth be x
• Length=4x

We know

`\boxed{\sf Area=Length* Breadth}`

`\\ \sf\longmapsto x(4x)=36`

`\\ \sf\longmapsto 4x^2=36`

`\\ \sf\longmapsto x^2=(36)/(4)`

`\\ \sf\longmapsto x^2=9`

`\\ \sf\longmapsto x=√(9)`

`\\ \sf\longmapsto x=3`

• Breadth=3m
• Length=4(3)=12m
