Question

Area of a square with side $\left(7cd\right)$ m is square metre.

• A. $49c^{2}d$
• B. $49c^2{d}^2$
• C. $47c^{2}d$
• D. $44c^2{d}^2$

Answer 1

The correct option is B $49c^2{d}^2$

Given:
Side of square $=7cd$ metre
Area of the square = Side $\times$ Side
$=7cd\times 7cd$
$=7\times 7\times cd\times cd$
$=\left(49c^2{d}^2\right)m^2$
