Height is length and base is width. Therfore, width is 9 (cm) and length is 4 (cm) which gives us an area of 36 cm sq.
The face of a US nickel is circular so it has a diameter, not a length and width. According to the US Mint the coin is 21.2 mm in diameter and 1.95 mm thick.
The height of a normal letter-size paper (also known as US Letter) is 11 inches, while the width is 8.5 inches.
-- Measure the length, width, and height of the aquarium, in inches. -- Multiply (length) x (width). -- Multiply that result by (height). -- Divide that result by 231. -- Now you have the capacity in gallons, up to the rim.
The perimeter of a rectangle is equal to 2 times the sum of the length and the width, which we can write as P = 2 (l + w). We know the perimeter is 12 therefore 12 = 2 (l + w) l + w = 12 /2 l + w = 6 So now we need to find pairs of integers (not including 0, for a rectangle can't exist with a dimension of 0) which add up to 6. The pairs are: 1 & 5, 2 & 4 or 3 & 3. This gives us 5 possible combinations: Length = 1 Width = 5 Length = 2 Width = 4 Length = 3 Width = 3 Length = 4 Width = 2 Length = 5 Width = 1
