Question

What is the area of the rectangle , whose length is $5\sqrt{3}cm$ and breadth is $5cm$.

• A. $43.3c{m}^2$
• B. $\sqrt{75}c{m}^2$
• C. $25c{m}^2$
• D. None of these

Answer 1

Answer: (A)

$43.3c{m}^2$

Area of rectangle having length $l$ and breadth $b=l\times b$

If $l=5\sqrt{3}cm$ and $b=5cm$, then Area$=5\sqrt{3}\times 5c{m}^2=25\sqrt{3}=25\times 1.73=43.25c{m}^2$
