Question

Find the area of an equilateral triangle whose side is 8 m. Give your answer correct
to two decimal places.
​

Answer 1

Answer:

Area of equilateral =√3a²/4 = 64√3/4 = 16√3

Answer 2

It is given that

Side of equilateral triangle = 8 m

We know that

Area of equilateral triangle = √3/4 (side)2

Substituting the values

= √3/4 × 8 × 8

By further calculation

= √3 × 2 × 8

= 1.73 × 16

= 27.71 m2
