Answer:
To find the area of triangle KLM, we need to use the given information about the triangle's sides and the fact that angle K is a right angle.
From the search results, we don't have an exact match for the given side lengths of triangle KLM (30 cm, 78 cm, and 84 cm). However, we can still proceed with finding the area using the formula for the area of a right triangle.
The formula for the area of a right triangle is:
Area = (1/2) * base * height
In this case, side LK (30 cm) is the base, and side LM (84 cm) is the height. Therefore, we can calculate the area as:
Area = (1/2) * 30 cm * 84 cm
Area = 1260 square cm
Therefore, the area of triangle KLM is 1260 square cm.
