area of a square = (side length)^2 area of triangle = (1/2)(base)(height) the side length of the square is 12 the base of the triangle is also 12 (it's the same length as the square) and the height is 6 so, let's start by finding 1. the area of the square 2. the area of the triangle

The area of the triangle is 36 in2, so she can create only 2 triangles. The area of the triangle is 72 in2, so she can create only 2 triangles. The area of the triangle is 36 in2, so she can create only 4 triangles. The area of the triangle is 72 in2, so she can create only 4 triangles.

not quite, remember that area = (side length)^2 what is 12^2?
anonymous
  • anonymous
so it would be 12 x 6?
Vocaloid
  • Vocaloid
no, 12^2 is the same as (12)*12

  • anonymous
omg sorry i did 12 x 2 i ment 12 x 12 144 sorry
Vocaloid
  • Vocaloid
right, so we know the area of the square (144) what is the area of the triangle?
anonymous
  • anonymous
72

hm, not quite remember: area of triangle = (1/2)(base)(height) base = 12 height = 6
anonymous
  • anonymous
so 12 divided by 6?
anonymous
  • anonymous
2
Vocaloid
  • Vocaloid
not quite.... area = (1/2)*base*height
Vocaloid
  • Vocaloid
(1/2)*6*12 = ?
anonymous
  • anonymous
36 sorry i didnt figure it out earlier
Vocaloid
  • Vocaloid
no need to apologize, that's why we're here! :) ok, so the total area of the square is 144, and the area of the triangle is 36, right? to find out the number of triangles she can make, we divide the area of the square by the area of each triangle so, what is 144/36?
anonymous
  • anonymous
4
Vocaloid
  • Vocaloid
great! so, she can make 4 triangles and each triangle has an area of 36 inch^2 so, which of the 4 answer choices do you think it is now?
