Asquare is shown below. which expression can be used to find the area, in square units, of the shaded triangle in the square? fraction 1 over 4 ⋅ 6 ⋅ 6 fraction 1 over 2 ⋅ 3 ⋅ 3 fraction 1 over 4 ⋅ 3 ⋅ 3 fraction 1 over 2 ⋅ 6 ⋅ 6

The area of a square would me multiplying the width times the length and then multiplying by one half would be like splitting the square in half so your answer would be that last one right there. 6*6= area then multiply by 1/2 = half of area  Hope this helps! :D 

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
