The formula for the area of a rectangle, which is the shape of a door is:
A=l*w Where l is the length and w is the width of the shape.
The length of the door is 84 inches
l=84 in
The width of the door is 54 inches
w= 54 in
now lets plug in the information into the formula
A=l*w
A=84*54
A=4536 in²

Answer:
78
Step-by-step explanation:
50 questions worth 2 a piece and you miss 11 questions so we are going to take 2(11) off of 50.
We are doing 100-2(11).
100-22=78.
Or if you miss 11 questions you get 39 right. So 39(2)=78.
X=10 because........
the opposite of 1/2=times 2
20 times 2=40
40 divided by 4=10, so
x=10
