Question

Area of an
equilateral Triangle is 365 cm^2.Find the perimeter.

Answer 1

Answer:

Perimeter of equilateral triangle = 87.09 cm

Step-by-step explanation:

Area of equilateral triangle = 365cm^2

root3/4 × a^2 =365 cm^2

0.433 × a^2 = 365

a^2 = 365 ÷ 0.433

a^2 = 842.95

a = root 842.95

a= 29.03 cm

Perimeter of equilateral triangle = 3a

= 3 × 29.03

= 87.09 cm
