Question

find the perimeter and area of an equilateral triangle whose height is 12 CM. write your answer, correct to 2 decimal places​

Answer 1

Answer:

Hi,

Height of the equilateral triangle

(h ) = 12 cm

Side (a) = ( 2h )/ V3

= ( 2 x 12 )/ V3

= (83)/ 13

= 8V3 cm

Perimeter = 3a

= 3 x 8V3

= 24v3 cm

Area = ( 13/4) a?

= ( v3/4) (8V3)2

= 48V3 square cm

I hope this helps you.
