What is the surface area of the pyramid?
HELP!!

31200

Step-by-step explanation:

pyramid surface area = base x 2 x  first triangle surface area x 2 x second triangle surface area

20 x 2 x 13 x 2 x 1/2 x 12 x 10 x 1/2 =

40 x 13 x 12 x 5 = 40 x 60 x 13 = 2400 x 12 = 31200

the area is 31200

hope it's correct
