The length is 3 feet
15 feet
length + width = ½ perimeter ie 24', so length = 24 - width length = 2 x width + 3, so 24 - width = 2 x width + 3 ie 21 = 3 x width so width = 7 and length = 17
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
Perimeter = 2*(width + length) = 2*(8/12 + 2)feet = 2*(2/3 + 2) feet = 2*8/3 ft = 16/3 ft or 51/3 ft = 5 ft 4 inches

Let the width be x feet. Then, the length would be (x+7) feet. Given that decreasing the length by 3 feet and increasing the width by 2 feet gives a perimeter of 32 feet, you can set up the equation 2( (x+7) - 3 + x + 2) = 32 to find the original width x and length (x+7).
length + width = ½ perimeter ie 24', so length = 24 - width length = 2 x width + 3, so 24 - width = 2 x width + 3 ie 21 = 3 x width so width = 7 and length = 17
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
the length of a rectangular garden is 2 feet longer than 3 times it's width .if the perimeter of the garden is 100 feet find the width and length of the garden
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
Assume it is a rectangular window (why?) Suppose the width is L feet. Then the width is L + 3 feet (Odd, because normally Length is the larger of the two) So Perimeter is 2(Length + Width) ie 38 = 2*(L + L+3) 19 = 2L + 3 16 = 2L L = 8 and then L + 3 = 11 So the window is 8 feet long and 11 feet wide.
Perimeter = 2*(width + length) = 2*(8/12 + 2)feet = 2*(2/3 + 2) feet = 2*8/3 ft = 16/3 ft or 51/3 ft = 5 ft 4 inches
Perimeter = length + width + length + width = 2 x (length + width) Given: perimeter = 22in length = width + 3in Thus 22 = 2 x (width + 3 + width) 11 = 2 x width + 3 8 = 2 x width 4 = width So the width is 4in.
