How do you find the length of a rectangle knowing ONLY the diagonal and the length?
If by that you mean knowing only the diagonal and the width, then by the formula a2+b2=c2, where a is the length, b the width and c the diagonal. To find the width b, you need to calculate sqrt(c2-a2). For example, the width of a rectangle with length 3 and diameter 5 is sqrt(52-32)=4
What is the height of a 15 inch tv when the width is 12 inch?
This question can be solved using pythagorus, assuming the screen is a rectangle and 15in is the measurement of the diagonal (hypotenuse) of the screen. a2 = c2 - b2 a2 = 152 - 122 a2 = 225 - 144 = 81 a = 9in
If the cardboard has centimeters each sides what is the area?
If it's rectangular, you need to multiply length x width, to get the area. If the sides are expressed in cm, the area will be in square cm.
How long is an A2 piece of paper in meters and centimeters?

How do you find the volume in a cardboard that is 12 cm long 2 cm wide and 3 cm high?
You multiply [ Length x Width x Height ]. You get a volume of [ 12 x 2 x 3 = 72 cubic cm ]
