An equilateral triangle has a perimeter of 78 cm.

If the height of the triangle is 15.5 cm, what is the area of the triangle?

The area of the triangle is : 201.5 cm ²

Step-by-step explanation:

All the sides of an equilateral triangle are equal. A triangle has 3 sides. If the perimeter is 78cm, 78 cm needs to be divided by 3 so find each side of the triangle.

78:3=26

In order to find the area of a triangle, you need to multiply the base by the height and divide the product by 2.

26*15.5=403

403:2 = 201.5

So therefore, The area of the triangle is : 201.5 cm ²
