126 / 9 = 14cmRemember:Area = Length x WidthWhich can be written as...Length = Area / WidthOr...Width = Area / Length
35 and 28
Both the width and length have been increased by 4 feet and so 9*14 = 126 square feet
If "50 inches" is the perimeter all you can say is that length plus width = 25 inches.
length 18 width 7
The perimeter is found by multiplying the width by the length. So divide 50 by 12 and you get 4.166 width.
50 diameter to length
Assuming that the length is at least as great as the width, the length can have any value, L, between 25 and 50 feet. The width, W, then would be 50 - L feet.
If it is a rectangle, the the dimension of Area [Distance²] is (Length) x (Width).So if the the length and width do not have units, then just say 'it is 50 units long' then the area is 1250 units²
Length + width = ½ perimeter, ie 42 yards or 126 feet. L = 6 W so w = 126/7 = 18 feet and length is 108 feet ie 36 yards.
Perimeter = 2 lengths and 2 widths In your case length + width = 25cm If length is 5cm more than width then length = 15cm and width = 10cm
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
