Given: Height is twice the base Formula Used: Area of triangle = ½ × Base × Height Calculation: Let assume that Base of the triangle = x units So, Height of the triangle = 2x units Area of triangle = ½ × Base × Height ⇒ Area of triangle = ½ × x × 2x ∴ Area of triangle = x2 Sq. units The correct option is 1 i.e. x2 Sq. units.
