Answer 1

hope ..it would help

Answer 2

Answer:

$15.588 cm^2$  

Step-by-step explanation:

Length of side of equilateral triangle is 60 mm.

10 mm = 1 cm

1 mm = 0.1 cm

60 mm = $60 \times 0.1=6cm$

So, Length of side of equilateral triangle is 6 cm

Area of equilateral triangle = $\frac{\sqrt{3}}{4}a^2$

Where a is the side of triangle

a = 6 cm

So, Area of equilateral triangle = $\frac{\sqrt{3}}{4}6^2$

                                                    = $15.588 cm^2$  

Hence the area of given equilateral triangle is  $15.588 cm^2$
