Question 985126
L=length; W=width; d=depth
.
The surface area (SA)of the pool can be given by:
SA=(perimeter*depth) + (length*width)
SA=((2(L+W))*d)+(LW)
SA=((2(6+4))*1.3)+(6*4)
SA=26+24=50m^2
ANSWER a: Area of tiles needed is 50 meters squared.
.
($40/m^2)(50m^2)=$2000
ANSWER b: It will cost $2000 to line the pool.
