Step-by-step explanation:
Multiply the density of the liquid or gas by how deep in the tank you want to calculate the pressure. For example, assume you have water with a density of 60 lb. mass per square foot (lbm/ft²) and you want to find the pressure 10 feet down the tank. So, 60 lbm/ft² times 10 feet equals 600 lbf/ft².

If you are asking for the area of the rectangle...
Let L = Length
Let W = Width
Let A = Area of rectangle
A = LW
A = ( 2x + 3 ) ( 4x - 1 )
A = 8x^2 - 2x + 12x - 3
A = 8x^2 + 10x - 3
If you are asking for the perimeter of the rectangle...
Let L = Length
Let W = Width
Let P = Perimeter of rectangle
P = 2L + 2W
P = 2 ( 2x + 3 ) + 2 ( 4x - 1 )
P = 4x + 6 + 8x - 2
Expanded form -
P = 12x + 4
Factorised form -
P = 4 ( 3x + 1 )
Hope this helps! :)
Have a lovely day! <3
Exchange : 63m = 6300 cm; 56m21cm= 5621cm
So the lengths of the ribbon will be left is : 6300 - 5621 = 679cm = 6.79 m
Hope it helps! If it is, Brainliest please!
