Question

The area of an equilateral
triangle that is 1613 sq.m, then
the cost of putting fence around
the plot at the rate of ₹10 per
metre is ?​

Answer 1

Answer:

Let Side of triangle = x m.

$\frac{ \sqrt{3} }{4} \times {x}^{2} = 1613$

${x}^{2} = \frac{1613 \times 4}{ \sqrt{3} }$

$x = \sqrt{ \frac{1613 \times 4}{ \sqrt{3} } }$

Required cost =

$4x \times 10 = 4 \times \sqrt{ \frac{1613 \times 4}{ \sqrt{3} } } \times 10$
