Surface Area of Triangles

How do you find the AREA of a TRIANGLE?

• Height x Base divided by 4

• Length x Width

• 1/3 (Length x width)

• 1/2 (Base x height)

Answer explanation

The area of a triangle can be found by multiplying the base and height and dividing the result by 2. This formula is derived from the concept that the area of a parallelogram is equal to the base multiplied by the height.

The base of the triangle is 5 inches. The length of the rectangle is 15 inches. The height of the triangle is 10 inches. Find the surface area.

• 300 inches

• 200 inches

• 275 inches

Answer explanation

The surface area of a triangle is calculated by multiplying the base and height and dividing by 2. In this case, (5 * 10) / 2 = 25 square inches. The surface area of the rectangle is calculated by multiplying the length and height, which is 15 * 10 = 150 square inches. Adding the two areas together, we get 25 + 150 = 175 square inches. Therefore, the correct answer is 275 inches.
