Question

The area of a rectangle is $800x^2$ and its length is $40x$. What is its breadth?

Answer 1

We know that the area of rectangle is with length $l$ and breadth $b$ is $A=l\times b$

Here, it is given that the area of rectangle is $800x^2$ and length of the rectangle is $40x$, therefore,

$800x^2=40x\times b\Rightarrow b=\frac{800x^2}{40x}=20x$

Hence, the breadth of the rectangle is $20x$.
