Answer 1

Step-by-step explanation:

Area Of equilateral triangle is= 25√3m²

To Find : = altitude and perimeter of triangle 3 singnificant figure

Solution : Let sides of triangle is a then, we know that the area of eqilateral triangle

25√3 = √3/4×a×a

a² = 100

a = 10m

Equilateral triangle perimeter = 3a= 30m

Altitude = (√3a) /2= (10√3) /2

= 5√3 = 8.660m

Answer. perimeter = 30m and altitude = 8.660m
