Answer 1

Step-by-step explanation:

1. Area of traingle

=½ × base × height

= ½ × 8 × 6

= 1 × 4 × 6

= 24 m²

2. According to the question

Sides of the triangular field are 50m ,65m ,65m.

Cost of laying grass in a triangular field= Rs7per m²

Let a = 50

b = 65

c= 65

S = ( a + b + c ) / 2

S = ( 50 + 65 + 65 ) / 2

= 180/2

= 90

Area of triangle= √s(s-a)(s-b)(s-c)

√90(90-50)(90-65)(90-65)

√90×40×25×25

= 1500m²

Cost of laying grass =. Area of traingle × cost per m²

= 1500×7

= Rs . 10500
