Question

If the breadth of Rectangle $1$ and Rectangle $2$ is $30$cm and $45$ cm respectively . The area of rectangle $1$ is $900c{m}^2$ and area of the rectangle $2$ is $1350c{m}^2$.Then compare the lengths of rectangle

• A. Both are same
• B. Length of rectangle $1$ is greater than rectangle $2$
• C. length of rectangular $2$ is greater than rectangle $1$
• D. None of these

Answer 1

Answer: (A)

Area of rectangle $1=900㎠$

$\Rightarrow$ Length$\times$ breadth$=900㎠\Rightarrow l_1=\frac{900}{30}=30㎝$

Area of rectangle $2=1350㎠$

$\Rightarrow$ Length$\times$ breadth$=1350㎠\Rightarrow l_2=\frac{1350}{45}=30㎝$

$\therefore l_1=l_2$
