Final answer:
The formula for the area of a triangle is 1/2 × base × height. In this case, the base of the triangle is given as 26 cm less than the height.
Step-by-step explanation:
The formula for the area of a triangle is 1/2 × base × height. In this case, the base of the triangle is given as 26 cm less than the height of the triangle. Let's assume the height is x cm, then the base would be x - 26 cm. The area of the triangle can be calculated as:
Area = 1/2 × (x - 26) × x
After simplifying, we get:
Area = 1/2 × (x^2 - 26x)
So the area of the triangle in square centimeters is given by the expression 1/2 × (x^2 - 26x).
