Question

Find the area of ∆ whose sides are 50 m , 65 m and 65 m.​

Answer 1

Answer:

Given:-

Sides of the triangle are a=50m, b=65m, c=65m

Area of triangle, by Heron's formula =

√s(s−a)(s−b)(s−c)

Where,

s= $\huge\frac{a + b + c}{2}$

s= $\huge\frac{50 + 65 + 64}{2}$

s = 90

Area of triangle = √90(40)(25)(25)

Area of triangle = 1500m²

Cost of laying grass = Area × 7

Cost of laying grass =1500 × 7

Cost of laying grass = Rs 10500
