#### Answer

The area of the triangle is $30 in^2$.

#### Work Step by Step

The formula that we need to use to solve for the area of the triangle is:
$A=1/2 bh$
I am first going to convert the length of the base and the hypotenuse into inches.
BASE:
$1ft=12in$
HYPOTENUSE:
$1 ft 1 in. = 13in$
I am going to plug in the numbers into the formula:
$A=1/2bh$
$A= 1/2(12)(5)$
$A=1/2(60)$
$A=30$
The area of the given triangle with the base of 12 and the height of 5 equals:
30in^2
