Question

The cost of painting a triangular patch was 13248 . If the base of the triangle was 2 . 4 m , find its । altitude The rate of painting the patch is १ 120 per 5m

Answer 1

Answer

Explanation

Total Cost = Area of Triangle x Cost/Area

₹132.48 = Area of Triangle x ₹120/5m

∴ Area of Triangle

= (132.48 x 5) / 120

= 5.52m²

Now,

Area of Triangle = 1/2 x (bh)

⇒ 5.52 = 1/2 x 2.4 x h

∴ h = (5.52 x 2) / 2.4

= 4.6m

Answer 2

Answer:

4.6 m

Explanation:

Area of triangle = 132.48 × 5/120

= 5.52 m2

therefore, 1/2 × base × height

5.2× 2/2.4

= 4.6m
