Question

The length of a rectangle is twice its breadth. The area of the rectangle is 450cm2 what is the length and breadth? (Please explain in a simple way)

Answer 1

Answer: 30, 15 cm

Step-by-step explanation:

Given

The length of the rectangle is twice its breadth

The area of the rectangle is $450\ cm^2$

Suppose the breadth is x

So, the length is 2x

The area can be written as

$\Rightarrow 2x\times x=450\\\\\Rightarrow x^2=225\\\\\Rightarrow x=15\ cm$

breadth is 15 cm, length is 30 cm
