If the area is 15ft, and the length is twice the size of the width, x must be 5, and 2x is 10. 2x X x = 15 15 / 3 = 5 x = 3 2x = 5 sorry, i tried, i cant get it
15ft
15ft is 5 yds, so 15ft x 15ft is the same as 5yds x 5yds which would equal 25 square yards.
Cubic footage (or volume) is simply the length x width x thickness. 4 inches x 1ft/12 inches = 0.333 ft Therefore, the driveways volume is: 30ft x 15ft x 0.333ft = 149.85 cubic feet, or better to just say 150 cubic feet.
24ft x 15ft = 360 ft^2 = 360 square ft 360 square ft = 33.4 square meters
120 of them.
15ft
15ft
formula for area of a rectangle is length times width in this equation 15ft is your length and 10ft is your width so.... 15 x 10 = 150 your final answer is 150ft squared (150 feet squared)
let "X" be the unknown value 5X * 12X = 540 60X2 = 540 X2 =540 / 60 X2 = 9 X = 3 Therefore the actual length is 12*3 = 36 feet, Width is 5 * 3 = 15 feet Check: 36 ft * 15ft = 540 ft2
Perimeter: 150+15+150+15 = 330 feet Area: 150*15 = 2250 square feet
2*(length + width) = 54 feet.
Area = 15 times 8 = 120 square feet.
(Diagonal)2 = (15)2 + (8)2 = (225) + (64) = 289Diagonal = sqrt(289) = 17
135 square feet. Just multiply length by width - the answer is the square footage.
area (A) = length (L) x width (W) = 54 L = W+15 so..... (W + 15) x W = 54 then W^2 + 15W = 54 putting it in a form (aX^2 + bX + C = 0) so that a quadratic formula (look it up on Widipedia) can be used to solve it: W^2 + 15W - 54 = 0 a=1, b = 15, c = -54 Solving give us W = 3, which means L = 18
You multiply the width by the length to get the area. In this case the answer would be 240 square feet or 26.67 square yards.
Perimeter l+l+w+w= 70ft Area LxW =300 sqft
