Question

Perimeter of equilateral triangle is 24cm if its height is 6cm.find its area.

Answer 1

Answer:

This is an equilateral triangle.

Explanation:

So,

Let the sides of triangle be 'x'.

Perimeter = 24cm. (given)

x+x+x = 24

3x = 24

x = 24/3

and, x = 8.

Hence, all sides of triangle = 8 cm

and height = 6cm. (given)

so, area = 1/2×base×height

=1/2×8×6

=1/2×48

=24 cm square.
