Let's Apply Directions:
Solve each problem using any of the four methods in solving quadratic equations. The quadratic equation for each item is already provided for you.
1. Find the length of a square table whose area is 81 in². Equation: x²=81, (x represents length of the the table)
2. The area of a rectangular billboard is 48 ff. How much fencing will be needed to enclose it if its length is 2 ft longer than its width? Equation: w (w + 2) = 48, (w represents the width of the billboard)
3. Find the length of the base of a triangular park with an area of 800 m² if the altitude is 60 m longer than the base. Equation: 800 = b (b +60), (b represents the length of the base of the triangular par
