The diagonal of a rectangle measures 13 cm. The width of the rectangle is 5 cm.

so the diagonal makes a right angle triangle so we have two sides one side is unkown

so using pythogores theorm

width^2 + length^2 = diagonal^2

5^2 + length^2 = 13^2

25 + length^2 = 169

length^2= 169 - 25

length^2 = 144

length = 12
