Lateral Surface Area of a square pyramid (4 isosceles triangles): For the isosceles triangle Area = (1/2)Base x Height. Our base is side length a and for this calculation our height for the triangle is slant height s. With 4 sides we need to multiply by 4. (hope this will help)
498 is approximately 500
12 is approximately 10
500/10 = 50
So, 498/12 is approximately 50.
I'm pretty sure it's 28 but sorry if I'm wrong it might be 44
