The perimeter of a rectangle is 14cm. If the diagonal is 5cm, find the dimensions of the rectangle.
L=Length; W=width; D=Diagonal; P=perimeter=2(L+W)
square each side
P=2(L+W)
14 cm=2(L+W) Divide each side by 2.
7 cm=L+W Subtract W from each side
7 cm-W=L
Substitute for L
Subtract 25 cm from each side.
