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

$\boxed{\sf Area=Length\times Breadth}$

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

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

$\\ \sf\longmapsto x^2=\dfrac{36}{4}$

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

$\\ \sf\longmapsto x=\sqrt{9}$

$\\ \sf\longmapsto x=3$

• Breadth=3m
• Length=4(3)=12m
