SOLUTION: The lateral surface area of a right square pyramid at the right in the figure above is given by S = b times the square root of b^2+4h^2. If the pyramid has height 10 feet and later

Question 1132558: The lateral surface area of a right square pyramid at the right in the figure above is given by S = b times the square root of b^2+4h^2. If the pyramid has height 10 feet and lateral surface are 100 square feet, what is the length of the side b of its base?

This is a quadratic equation with "b^2" as the variable. The expression does not factor, so use the quadratic formula to find the value of b^2; then take the square root to find b.
