Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve

Area of bottom: 20 x 10 = 200
Area of front: 20 x 15 = 300
Area of back (same as front) = 300
Area of right side: 10 x 15 = 150
Area of left side (same as right side) = 150
Total of all the sides: 1100
