The ratio of the longer side of a rectangle to its shorter side is 4 to 3. if the shorter side of the rectangle is 21ft, what is the length of its longer side?

28 ft

Step-by-step explanation:

Let longer side of rectangle be and the shorter side be  , thus we can write the ratio:

Now putting 21 into S, we solve for L:

Hence, length of longer side is 28 ft.

28 feet

Step-by-step explanation:

We know that the ratio of the longer side of a rectangle to its shorter side is 4 to 3.

The length of the shorter side of the rectangle is 21ft and we are to find the length of its longer side.

For that, we can use the ratio method:

Therefore, the length of the longer side is 28 feet.

ian gonna lie that is way to much

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
