Question

The length of one side of the rectangles is twice the length of its adjacent side.If the perimeter of rectangle is `60cm` find the area of rectangle

Answer 1

Given:

length=l ; breadth(b)=2l

length(l) = 10cm

breadth(b) = 20cm

`\begin{gathered} \text{Area of a rectangle=l}* b \\ \text{Area of a rectangle}=10*20 \\ \text{Area of a rectangle}=200cm^2 \end{gathered}`
