The answer is 56 ft

The perimeter of the rectangle with width w and length l is:
P = 2w + 2l

We know:
w = 7 ft
l = 3w = 3 * 7 = 21 ft

P = 2w + 2l
P = 2 * 7 + 2 * 21
P = 14 + 42
P = 56 ft

If the perimeter (the distance around) of a rectangle is 54 inches and its width is 12 inches, how long is the rectangle?
Liula [17]

Answer:

15 in

Step-by-step explanation: It would be 15 in because 12+12 equals 24 and 50-24=30 and 30 divided by 2 equals 15 in.

Divide 36 books into two groups so the ratio is 5 to 7. (Use the double number line strategy)
lutik1710 [3]

A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)


So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.


P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)

A 24 foot ladder is placed against a building at an angle of 75⁰. How far is the bottom of the ladder from the building?
yanalaym [24]
24ft is the hypotenuse, at an angle of 75<span>⁰, and we need to find the adjacent.

We use cos(), which is adjacent divided by hypotenuse.

Therefore, we can find the adjacent by doing:

25 * cos(75) = 6.47ft

Round the answer however you like.</span>
