Find the lateral area and surface area of a regular triangular prism with base edge 7 cm, a base height 6.1 cm and prism height of 11 cm. round to the nearest tenth.

Lateral Area: 288 cm

Total Surface Area: 331 cm

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
