Answer 1

Step-by-step explanation:

20

because

60÷3=

=20

I think this is correct answer

Answer 2

Answer:

173.21 m²

Step-by-step explanation:

One side of the equilateral triangle (a) = perimeter/3 = 60/3 = 20m

Area of an equilateral triangle = √3/4 * a²

√3/4 * 20 * 20 = √3 * 5 * 20 = √3 * 100 m² = 1.7321 * 100 = 173.21 m²

Hence, the area of the triangle is 173.21 m².
