An equivalent fraction in higher terms is 9/12 because you must multiply the top by 3 because you multiplied the bottom by 3
Recall that the equation to find the perimeter of a rectangle is 2(L + w)
Since we know the length, we can make an equation:
2(3 + w) = 12
Divide both sides by 2:
(3 + w) = 6
w = 3
Now that we know both length and width, we simply have to find their product to solve for area:
a = L * w
a = 3 * 3
a = 9
The area of the rectangle is 9 cm^2.
X = third angle
82° + 62° + x = 180°
144° + x = 180°
x = 36°
The answer is 49.6
