Wouldn't it be 1/18x?????
P=18 because 3 times two is 6 and 4 times 3 is 12 so when you add them you get 18

Answer: 7 Inches
Step-by-step explanation:
From the above question, we were provided with the height of the triangle which is 12 Inches and the subsequent area which is 42, and the question was to find the base of the triangle. One of the formula for the area of a triangle is the:1/2(b*h).
From here,we substitute h for the value 12 and we will have 1/2(b*12)=84.Cross multiply and we have something looking like this:12b=84,then divide both sides by 12 and we have our answer as 7 inches.
