Question
If the area of a triangle is 1080 cm2 and
base: corresponding altitude is 3:5, 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 3x and 5x respectively. According to question, ⇒ 1/2 x base × altitude = 1080 cm2 or, ⇒ 1/2 x (3x) x (5x) = 1080 ⇒ 15x2 = 2160 ⇒ x2 = 2160/15 ⇒ x2 = 144 ⇒ x = √144 ⇒ x = 12 cm Altitude of a triangle = 5x = 5 × 12 cm = 60 cm
