195.00 in²
1) Since this rectangular prism has as a base a rectangle whose is 15 x 13 since the area of a rectangle is the product of the width by the height we can write out:
[tex]\text{Area}_{\text{base}}=15\cdot13\text{ =195}[/tex]
2) So the area of the base is 195 in²
3) Hence, the area of the base is 195.00 in²
