• A. $b^2$
• B. $b(a-b)$
• C. $(a-b{)}^2$

Answer 1

The correct option is C $(a-b{)}^2$

$\underset{–}{ConceptInvolved}$:
Area of a square with side $a=a^2$ square units.
And area of a rectangle with sides $l$ and $b=lb$ sqare units

$\underset{–}{Method}$:
In the given square,
Area of the Orange colored box$=(a-b)\times (a-b)=(a-b{)}^2$ square units.
Area of the Blue colored box
$=b\times (a-b)=b(a-b)$ square units.
Area of the Green colored box
$=b\times b=b^2$ square units.
Area of the Red colored box
$=(a-b)\times b=(a-b)b$ square units.
