Each side of an equilateral triangle measures 8cm. Find:

(i) The area of the triangle, correct to 2 places of decimal

(ii) The height of the triangle, correct to 2 places of decimal.

Take =1.732

(i) We know that,

Area of an equilateral triangle = sq units

It is given that, each side of equilateral triangle is of 8 cm

Therefore,

Area = × 8^{2}

=

=

= 1.732 × 16

= 27.712

= 27.71 cm^{2} (Up to 2 decimal places)

(ii) We also know that,

Height of an equilateral triangle = a

= × 8

=

= 1.732 × 4

= 6.928

= 6.93 cm (Up to 2 decimal places)
