Final answer:
To find the missing side of the triangle with an area of 252525 units^2, use the formula for the area of a triangle and solve for the missing side.
Step-by-step explanation:
To find the missing side of the triangle, we need to know the formula for the area of a triangle, which is 1/2 × base × height. Since we are given the area of the triangle as 252525 units2, we can set up the equation as 1/2 × base × height = 252525. We can then solve for the missing side by substituting the given value of either the base or the height into the equation and rearranging.
