2. Find The Area Of The Triangle.

Answers

Answer 1

Question:

Find the area of the triangle.

Answer:

198

Step-by-step explanation:

Take half of the Triangle

28/2 = 14

multiply length and width

                 14        x      28    =

392 but because it is a triangle you divide by 2

392 / 2 =   196 and add the other side

196 + 196 = 198 is the answer.
