Atriangle has an area of 227.04 square inches. the length of the base of the triangle is 47.3inches. what is the height?

A triangle's area S=0.5*base*height

so we know 227.04=0.5*47.3*height

height=9.6inches

height=9.6inches

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
