The perimeter is 2 times the length plus 2 times the width.
L = 3x + 2y
Capacity = (1/2) x (length) x (width) x ( [height of short end] plus [height of tall end] )
If the width is 9' and the length is twice that, the length is 18'; the perimeter is twice the length plus twice the width, which is 36' + 18' = 54 feet.
Perimeter: Add the length of the four sides. Area: Multiply length x width.
The equation to find the volume of a rectangular object is (a) volume equals length times width times height.
it equals LxL+WxW
a rectangle
length plus width equals perimetre
Length plus height plus width.
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
a = L x W: area equals length times the width. p = 2L + 2W: perimeter equals 2 times the length plus 2 times the width so L = (p - 2W)/2

Perimeter = 2(Length + Width) = 2*(x+1 + x-3) =2*(2x - 2) = 4*(x - 1)
perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.
