If the dimensions are in feet then 10 times 30 = 300 square feet
150 ft * 160 ft = 24 000 square feet. 4 000 sq feet of lawn requires one pound of seeds so 24 000 sq ft of lawn will require 6 pounds of seed.
PF = ( 4.5 lb / 1000 sq ft ) ( 2500 sq ft ) = 11.25 lb fertilizer needed

300 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
450 sq. ft
the answer is 160x144
15 square yards = 135 square feet. (To repeat this type of calculation, just multiply square yards by 9 to get square feet).
Tom can mow 1,125 square ft of lawn in 1 hour.
150 ft * 160 ft = 24 000 square feet. 4 000 sq feet of lawn requires one pound of seeds so 24 000 sq ft of lawn will require 6 pounds of seed.
It depends on the shape. Let's say your lawn is 1 foot by 100 feet, which equals 100 square feet, then the surrounding measurement, called the 'perimeter', is 1+ 1+ 100+ 100 = 202 feet. Or, if the lawn is, say, 4 feet by 25 feet, which equals 100 square feet, the perimeter is 4+ 4+ 25+ 25 = 58 feet. If the lawn is perfectly square, its size would be 10 feet by 10 feet, and the perimeter is 10+ 10+ 10+ 10+ = 40 feet. The same is true for all dimensions in between: the perimeter changes as the shape of the lawn changes.
To find the total number of blades of grass in Landen's front lawn, first calculate the area of the lawn in square inches. The area is 20 feet × 80 feet = 1,600 square feet. Since there are 144 square inches in a square foot, the area in square inches is 1,600 × 144 = 230,400 square inches. Multiplying this by the number of blades per square inch (120), the total number of blades of grass is 230,400 × 120 = 27,648,000 blades.
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...
21,780 sq ft = 1/2 acre, or approximately a 200 x 100 lot.
PF = ( 4.5 lb / 1000 sq ft ) ( 2500 sq ft ) = 11.25 lb fertilizer needed
3.1 meters (3.0988m to be more accurate) or If the pool is 244 inches deep, then it's half way.
