A rectangle is 9 ft long and 40 in wide. What is its perimeter in inches?

Answer 1

Jayden Jackson

#"296 in"#

First, convert the #"9 ft"# long side into inches.

Since there are #"12 in"# in #"1 ft"#,

#"9 ft"xx12="108 in"#

Thus, the two sides of the rectangle are #40# and #"108 in"#.

The perimeter of a shape is just the sum of all its side lengths. Every rectangle has two pairs of congruent sides, so its perimeter can be evaluated through the expression

#40+40+108+108#

which equals

#"296 in"#

To find the perimeter of the rectangle, you need to add up the lengths of all four sides.

Given that the rectangle is 9 feet long and 40 inches wide, convert the length from feet to inches.

1 foot = 12 inches

So, 9 feet = 9 * 12 = 108 inches

Now, add up all four sides:

Perimeter = 2 * (length + width) Perimeter = 2 * (108 inches + 40 inches) Perimeter = 2 * (148 inches) Perimeter = 296 inches

Therefore, the perimeter of the rectangle is 296 inches.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
