What is the lateral area of the rectangular prism?

Assume the prism is resting on its base.



A.
135 in2

B.
270 in2

C.
300 in2

D.
310 in2

Answer 1

im thinking b

Answer 2

The lateral area of a rectangular prism is Ph, where P is the perimeter of the base and h is the height. The height is displayed as 15, so now we need to find the perimeter of the base (add the lengths of each side of the base):
P = 4+4+5+5=8+10=18
Now substitute the values into the equation:
L.A (Lateral Area) = 18(15) = 270.

So you’re right, it is b.

Happy studying! :)
