How To Find The Missing Dimension Of A Rectangle?

67.8cm

There is no way you can find about the other 3 sides without having some other information. The opposite sides of a rectangle are equal. This law will give you information about two sides i.e Length of two sides is equal to 15 cm. Now in order to know the other two sides, you must either know the measurement of the diagonal of the rectangle, or its area or its perimeter. Other wise you can not find the other two sides.

Perimeter=46mi and 20mi

L=12 ft
w= 8 ft
v= 288ft
?= h

You would see which one would make the most sense it depends on the number used and I would be able to explain it better
