Question

10. Find the area of a grazing field in the form of an
equilateral triangle fenced with a wire of length
66 m. (Take √3 = 1.73)​

Answer 1

Step-by-step explanation:

A=√3/4*a²

so here the perimeter of the given wire is 66 metre and we know that the length of the sides of an equilateral triangle is equal

therefore the the length of the side of the given equilateral triangle is 22 metre

putting the value in the formula of finding the area of an equilateral triangle-

A=√3/4*a²

A=√3/4*22*22

after solving we get-

*A≈209.58*

therefore the answer will be 209 metre #
