Final answer:
The area of a triangular shaped metal plate with a base of 10 feet and a height of 15 feet is 75 square feet. The thickness of the plate does not affect its surface area.
Step-by-step explanation:
To calculate the area of a triangular shaped plate, we have to use the formula for the area of a triangle, which is 1/2 * base * height. In this case, the base of the triangle is 10 feet and the height is 15 feet. So, the area will be 1/2 * 10 * 15 = 75 square feet.
Please note, the plate's thickness does not affect the calculation of its surface area. The thickness would be considered if we were asked to calculate the volume of the plate.
