Question

A rectangle is formed by keeping two squares next to each other. The length of the sides of each square is 10 cm.

What is the area of the rectangle formed by these two squares?

• A. $100c{m}^2$
• B. $200c{m}^2$
• C. $300c{m}^2$
• D. $400c{m}^2$

Answer 1

The correct option is B $200c{m}^2$

Given: The length of the sides of each square is 10 cm.
For the rectangle formed:
Length = 10 cm + 10 cm = 20 cm
Breadth = 10 cm
Area of the rectangle = Length $\times$ Breadth = $20cm\times 10cm=200c{m}^2$
