Question

Find the Area of the Triangular field of sides 55 m, 60 m, and 65 m. Find the cost of laying the grass in the triangular field at the rate of Rs 8 per m2​

Answer 1

Answer:

Cost of laying grass = Rs 12296.32

Step-by-step explanation:

The 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=  a+b+c/2

​ ⇒ s=  55+60+65/2

​ ⇒ s=90

Area of triangle =   √90(35)(30)(25)

​ Area of triangle = 1537.04m  

Cost of laying grass = Area ×8

Cost of laying grass =1537.04×8

Cost of laying grass = Rs 12296.32
