Answer:
108 in²
Step-by-step explanation:
Given that the legs of a right triangle are 12" and 18".
Be cause it is a right triangle (with 90 degrees between the legs), we can arbitrarily assign one of these to be the height and the other value automatically becomes the base.
Let 12" be height and 18" be base
area = 1/2 x height x base
= 1/2 x 12 x 18
= 108 in²
I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices:
If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph)
If it is 3, the line will go UP 3, over 1
If it is 1/3, the line will go UP 1, over 3
And if it it -3, it will go DOWN 3, over 1
(If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3)
Hope that helps!
