The area of the triangle ABC is 28cm2

Question

. Find the length BC if AB = 7.2cm.

Answer 1

We need more information to find the length BC. The area of a triangle is given by the formula:

Area = (1/2) * base * height

In this case, we are given the area (28 cm^2) and the length of AB (7.2 cm), but we don't have the height of the triangle.

If we had the height, we could rearrange the formula to solve for the base (BC):

Base = (2 * Area) / height

Without the height of the triangle, we cannot find the length BC.
