Find the missing side lengths of each rectangle, (a) and (c) or square (b) and (d). Homework Help ✎
To find the area of a rectangle, multiply the length
by the width.
(100 cm)(x cm) = 500 cm2
Solve for x.
Recall the properties of a square. All the side lengths must be equal.
Since one side is already given, you can conclude that the other side is also 8 cm.
