Question

Find the perimeter of an equilateral triangle given its area is 100√3msq​

Answer 1

Answer:

Step-by-step explanation:

Area of an equilateral ∆

= √3*a^2/4 = 100√3

= a^2/4 = 100

= a^2 = 400

= a=20cm

If length is 20 cm

Then the perimeter of triangle is

= 3 ×a

=3×20 cm

= 60 cm.

Answer 2

Answer:

Area of equilateral triangle = 100√3m²

area of equilateral triangle = √3a²/4

100√3 = √3a²/4

100 = a²/4

100×4 = a²

400 = a²

(20)² = (a)²

20 = a

a = 20m

side of equilateral triangle = 20m

Perimeter of equilateral triangle = 3×a

= 3×20

= 60m
