Solution: Let the given perimeter be P units and breadth be x units. Let the length be depicted by l. Since, Perimeter of a rectangle = 2 (l + b) ⇒ P = 2l + 2b ⇒ 2l = P – 2b ⇒ l = The

Math is a way of determining the relationships between numbers, shapes, and other mathematical objects.
By dividing both the sides by 2, the equation changes to 9 = l + w, or l + w = 9. STEP 3: Think of the possible dimensions the rectangle can have if the sum of the length and width equals 9 cm.
