• B. ${180}^{\circ }$
• C. ${90}^{\circ }$
• D. ${135}^{\circ }$

Answer 1

The correct option is A ${360}^{\circ }$

Sum of the interior angles of any quarilateral is ${360}^{\circ }$.
Since a rectangle is a quadrilateral whose opposites sides are parallel and equal the sum of its interior angle is ${360}^{\circ }$.
