A = 6s²
a) s = 3in, subtitute
A = 6 · 3² = 6 · 9 = 54 (in²)
b) s = 1.5 m, subtitute
A = 6 · 1.5² = 6 · 2.25 = 13.5 (m²)
1/2 is the answer try drawing models on paper to compare
Answer:

Step-by-step explanation:

The midpoints of the two diagonals are the same, so ...
D = A +C -B
D = (-7-3+3, -7.5+2.5+7.5)
D = (-7, 2.5)
Another way to look at it is that D will have the same x-coordinate as A and the same y-coordinate as C (in order to make each coordinate repeated twice).
The coordinates of point D are
(-7, 2.5)
