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

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

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
