Answer: 30, 15 cm
Step-by-step explanation:
Given
The length of the rectangle is twice its breadth
The area of the rectangle is [tex]450\ cm^2[/tex]
Suppose the breadth is x
So, the length is 2x
The area can be written as
[tex]\Rightarrow 2x\times x=450\\\\\Rightarrow x^2=225\\\\\Rightarrow x=15\ cm[/tex]
breadth is 15 cm, length is 30 cm
