Find the cost of lying grass in the given triangular field at the rate of ₹ 10 per Sq.metre if the area of the field is 325.50 square metre. |
|
Answer» Step-by-step explanation: Rs 10500 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
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 |
