To find the area of a rectangle, you use this equation/formula:
A = l x w
Since you know the area and the length, you can plug it into the equation:
A = l x w [A = 96 in² l = 8 in]
96 = 8 x w
To find the width, you divide 8 on both sides
12 = w
The width is 12 inches
To find the perimeter of a rectangle, you add all of the sides together:
P = l + l + w + w or P = 2l + 2w
Since you know the length and width, you can plug it in:
P = 2l + 2w
P = 2(8) + 2(12)
P = 16 + 24
P = 40 in

Answer:
40.5 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees, so to solve this all you need to do is add the two numbers you have and subtract them from 180.
62.5+77+x=180
139.5+x=180
-139.5 -139.5
x=40.5
