Afigure has vertices at the points (6,5), (6,-4), (-4,-4) and (-4,5). what is the area of the figure

  90 units²

Step-by-step explanation:

The rectangular figure is 10 units wide (from -4 to +6) and 9 units high (from -4 to +5), so its area is 10·9 = 90 square units.

Ithink it is d because if p=s1t-s2t then you just need to put it together backwards. and because it is a s1t and s2t are both multiples ,and you are trying to find what t is you will need to put t as the total and then divide p by s1 and s2. which this eliminates answers a and b, this will leave you c and d. so then compare both answers c and d, and since you are writing the equation backwards that will leave you only one answer which is d. so i believe that the correct answer is d.
