Can someone explain this to me

the question is mistyped.. they are trying to ask for the area.. not are.. :P s ... to answer the question that is trying to be asked.. and not the one that is being asked.. b/c there isn't really an answer to what is the are :/

Step-by-step explanation:

area of a triangle is 1/2 area of the box that the triangle makes 1/2  hmm , hence the fomula.. 1/2*base*height  b/c base*height is the area for a box... s ...

for this triangle it's 1/2* 3 * 4= 6  :)

note: even thou this is not a right triangle.. we still know the height of it.. the graph is showing us that.   so our formula still works... for this one  if we didn't know height.. we might have to use sin() or cos() to figure out height.. but here it's given. luckily  :)

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
