What do you need help with please attach so we can see thanks!
The formula for the area of the triangles is base x hight divided by 2 (bh/2)
The formula for the square is length times width (l x w)
therefore...
bh/2 = (12)(6) / 2 = 36 (this is the area of one triangle)
then you need to times 36 by 4 because you have 4 triangles.
36 x 4 = 144
l x w = 12 x 12 = 144 (this is the area of the square)
last you need to add the area of the triangles (144) and the area of the square (144) because that will give you the total surface area of the shape.
144+144= 288
so your answer is 288cm squared (288cm2)

I think it’s B I had the same question on my homework so that’s what I put sorry but it’s wrong!!
Answer:
20 candles is 50 dollars
Step-by-step explanation:
set up a proportion. you know what 4 candles is. that's ten dollars.
4/10 = 20/x
x will be your placeholder for the cost, because we don't know how much 20 candles is. now, make sure everything is lined up, obviously it'll be different on here. I'll post a picture of the work at the bottom.
take 4 and cross multiply it to X. that's 4x. then you'll take 10 and multiply it by 20. mental math, that gives you 200. so, now you've got a one step equation of 4x=200.
take 4 divide it into 200, and you get 50. hope this helps!!
