Question

If the height of an equilateral triangle is 3 cm. Then find the area of the triangle.

Answer 1

Answer:

4.5 sq. cm

Step-by-step explanation:

For equilateral triangle height = base

Then height = 3cm

Similarly base = 3 cm

Area of triangle = 1\2(b*h)

= 1\2(3*3)

= 1\2(9)

= 9\2

=4.5 sq.cm

The area of triangle is 4.5 sq. cm
