Question

find the area of the triangular field of size 55m,56m and 65m find the cost of laying the grass on in the triangular field at the rate of rs 8 per m²​

Answer 1

Step-by-step explanation:

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=

2

a+b+c

s=

2

50+65+65

s=90

Area of triangle =

90(40)(25)(25)

Area of triangle = 1500m

2

Cost of laying grass = Area ×7

Cost of laying grass =1500×7

Cost of laying grass = Rs 10500

Answer 2

Answer:

Find the cost of laying grass in a triangular field of sides 50 m, 65 m and 65 m at the rate of rupee 7 per m^(2). AB=a=50 m, BC=b=65 m and CA=c=65m. Hence, the cost of laying grass in a triangular field is rupee 10500.
