A triangle with a height of 12
inches has an area of 42 square
inches. How long is the base of
the triangle?

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.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
