Question

Find the area of equilateral triangle in m² whose each side is 40cm​

Answer 1

Answer:

In a equilateral ∆

Sides = 40cm

Area = ¶

=> area of equilateral ∆ = √3\4(a^2)

=> √3/4(40×40)

=> √3/4 (1600)

=> 692 cm^2

Answer 2

Answer:

side= 40 CM

area = ?

area of equilateral triangle= √3/4(s) ^2

=> √3/4× 40×40

√3/4×1600

√3×400

692.82 CM ^2

1cm ^2 = 1/10000 m^2

692.82 cm^2= 692.82/10000m^2

=> 0.069282 m^2
