15. The area of a rectangular playground is 315 yd? The width of the playground is 6 yd longer than its
length. Find the length and width of the playground.

Answer 1

length 21yd

width 15yd

Explanation:

Actually it does factor

x(x+6)=315

x²+6x=315

x² +6x - 315 = 0

(x+21)(x-15) = 0

x= -21. discard as can’t have a negative distance

x=15

So dimensions are 15 and 21
