Question
If the area of a triangle is 363 cm2 and
base: corresponding altitude is 2:3, then the altitude of the triangle is:Solution
Using the formula, Area of the triangle = 1/2 x base x height Let the base and altitude be 2x and 3x respectively. According to question, ⇒ 1/2 x base × altitude = 363 cm2 or, ⇒ 1/2 x (2x) x (3x) = 363 ⇒ 6x2 = 726 ⇒ x2 = 726/6 ⇒ x2 = 121 ⇒ x = √121 ⇒ x = 11 cm Altitude of a triangle = 3x = 3 × 11 cm = 33 cm
