The area of a playground is 16 square yards. the length of the playground is 4 times longer than its width. find the length and width of the playground. (1 point)
length = 16 yd, width = 1 yd
length = 8 yd, width = 2 yd
length = 1 yd, width = 16 yd
length = 2 yd, width = 8 yd

Can someone check if i did this correct. it’s number 4 if you’re wondering.
