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

length = 21 yd, width = 16 yd

length = 26 yd, width = 21 yd

length = 16 yd, width = 21 yd

length = 21 yd, width = 26 yd

Respuesta :

Answer:

length = 16 yd, width = 21 yd

Step-by-step explanation:

A= l*w

336=l*w

w=5+l

336=l*(5+l)

l= 16, -21

length cant be negative so

l=16

plug l in to find w

w=21

Answer: length = 16 yd, width = 21 yd
