Question

a peice of a land is in isosceles triangle .rhe cost of painting the fence around the land at the cost of ₹12per meter is ₹8400. if the base of the triangle is of length 100m find the length of two equal sides​

Answer 1

Since it is an isosceles triangle two sides would be the same.

Base = 100m

Let us take both sides as 2x, (since, x + x)

Cost of fencing the field = 2x(12) + 100(12)

8400 = 24x + 1200

7200 = 24x

7200/24 = x

x = 300m

The length of the other two sides, each is 300m.
