216 sqft squared feet

Step-by-step explanation:

6x6=36       36x6=216 your essentially finding the square and then adding a third dimension by multiplying it by its z value 2 dimensional objects have 2 dimension x and y. side to side(x) and up and down(y) when you add a 3rd dimension it adds another measurement which was 6 so you multiply the 2 dimensional object by the 3rd dimension and get the cube instead of square

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

maya’s expression will generate the wrong sum because she violated the commutative property.
