Answer:
Length = 8 in. Perimeter = 28 in.
Step-by-step explanation:
The equation for finding area is: A = l*w
Let's put the values we already know into the equation
48 = l * (6)
Divide both sides by 6 to isolate the l
8 in. = l
We know this answer is correct because 8 * 6 = 48
Now that we know that the length is equal to 8, we can solve for the perimeter.
To find the perimeter you have to add the values of all of the sides together.
Since we know that the top of a letter box is in the shape of a rectangle, we know that two of the sides are 6 in. and the other two sides are 8 in.
6 + 6 + 8 + 8 = 28 in.
Answer: length = 8 inches
Perimeter = 28 inches
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as Area = length × width
The width of the top of a letter box is 6 inches. The area of the top of the box is 48 square inches. Therefore,
Length = 48/6 = 8 inches
The formula for determining the perimeter of a rectangle is
expressed as
Perimeter = 2(length + width)
The Perimeter of the top of the box is
Perimeter = 2(8 + 6) = 2 × 14 = 28 inches
