Take any number, multiply by 15% and you have 15% of that number. 100x15% is 15. 15 is 15% of 100.
Unfortunately, "It Depends" - - To determine square footage, you have to know whether the lawn is square, rectangular, circular, or some other shape. Assuming a rectangle (or square), the square footage is determined by multiplying the length by the width. Linear footage is determined by adding 2 times the length plus 2 times the width. If the lawn is a square, there is only one answer (as there is only one solution which will give 1500 square feet: length and width of 38.73-some odd decimal, meaning 2 times length and 2 times width gives a linear footage of some 154.92 feet). However, if the lawn is rectangular, there are an infinite number of answers. Giving three examples to show the range: 1) If the lawn is 50 feet long by 30 feet wide, that will give (50x30), or 1500 square feet of area and ([50x2]+[30x2]), or 160 linear feet. 2) If the lawn is 100 feet long by 15 feet wide, that will give (100x15), or 1500 square feet of area and ([100x2]+[15x2]), or 230 linear feet. 3) If the lawn is an alleyway in the middle of a big city and 1500 feet long by 1 foot wide, that will still give the required (1500x1), or 1500 square feet of area...but a whopping ([1500x2]+[1x2]), or 3002 linear feet around! (Note that the square gives the least linear footage possible for a rectangular-shaped lawn) Have fun figuring out circular, elliptoid, and other funny shaped lawns...
Take any number, multiply by 15% and you have 15% of that number. 100x15% is 15. 15 is 15% of 100.
250x15= 500x7.5= 1000x3.75= 3750 100x15= 1500 250x15= 1500+1500+750= 3750
To find two numbers that multiply to 1500, we can factorize 1500. The prime factorization of 1500 is 2^2 * 3 * 5^3. To find the pair of numbers, we can combine these factors in different ways. One possible pair is 30 and 50, as 30 * 50 = 1500. So, 30 times 50 equals 1500.
20 is 15% of 133.33 (actually 133 1/3). To do this sort of problem, you first convert the percentage to a decimal by dividing it by 100 (in this case 15 / 100 = 0.15) and then you divide the number given by that decimal: 20 / 0.15 = 133.333333...
