An equilateral triangle's perimeter is 27 ft. The height of the triangle is 7.8 ft. What is the triangle's area?
You can Draw a Picture to solve this problem. Sketch and label the triangle. Find the perimeter and then use the area formula.
Area = (1/2) * base * height
Area = (1/2) * 27 ft * 7.8 ft
Area = 103.1 ft^2
