The area of a playground is 336 yd2 . The width of the playground is 5 yd longer than its length. Find the length and width of the playground

•  length = 26 yd, width = 21 yd
• length = 21 yd, width = 26 yd

• length = 16 yd, width = 21 yd

The length of a tropical garden at a conservatory is 5 feet more than its width.  A walkway 2 feet wide surrounds the outside of the garden.  If the total area of the walkway and garden is 126 square feet, find the dimensions of the garden.

• 2(x+2) + 2(x+7) = 126
• 2(x+4) + 2(x+ 9) = 126
• (x+2)(x+9) = 126
• (x+4)(x+11) = 126
