We know that the perimeter of a rectangle is twice the length, plus twice the width.
P = 2L + 2W
We also know that the perimeter is 156.
P = 156
Finally, we know that the width is 12 less than the length.
W = L - 12.
The next thing that we do is substitute the information that we have into the original equation:
P = 2L + 2W
156 = 2L + 2(L - 12)
From this point we start to solve
156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis
156 + 24 = 2L + 2L - 24 + 24
180 = 2L + 2L <--- getting like terms on same sides
180 = 4L <---combining like terms
180/4 = 4L/4 <--- getting like terms on same sides
45 = L <---now we have a value for L
Now we take the known value for L and substitute it in to our equation for W
W = L - 12
W = 45 - 12
W = 33
So now we have Length = 45 and Width = 33.
Given:
Total number of cars = 36
Each car has 2 red stickers and one blue sticker.
To find:
The expression that represents the total number of stickers on the 36 cars.
Solution:
Total number of cars = 36
Each car has 2 red stickers and one blue sticker. So,
Total number of stickers on each car = (2+1)
Total number of stickers on 36 car = 36(2+1)
= 36(3)
= 108
Therefore, the required expression for the total number of stickers on the 36 cars is 36(2+1) and the total number of stickers is 108.
Answer:
D. 129 1/6 square feet
Step-by-step explanation:
L x W = A is the equation used to solve for the area of quadrilaterals
When we substitute the values of L and W for what the length and width actually are, we end up with the equation 12 1/2 x 10 1/3 = A.
Now you just need to multiply the length and width which will give you 129 1/6 square feet.
