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
