Surface area = 2(?r^2) * height Insert your data and decide.

**PreAlgebra PLEASE HELLPPP**

Subtract 5h and add 16 to both sides.

**math**

SUM means to add. L = M + 2 L + M = 20 Substitute M+2 for L in the second equation and solve for M. Insert that value into the first equation to solve for L. Check by putting both values into the second equation.
