The area of a playground is 204 yd^2 the width of thr playground is 5 yd longer that its length what the length and the width of
morpeh [17]
W= width= L+5
L= length
Area= 204

Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)

0= L+17
-17= L

0= L-12
12 yards= L


WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.

w=L+5
w=12+5
w=17 yards


CHECK:
204=(12)(17)
204=204


ANSWER: The length is 12 yards and the width is 17 yards.

Hope this helps! :)

At what point do the curves r1(t) = t, 5 − t, 48 t2 and r2(s) = 8 − s, s − 3, s2 intersect?
DerKrebs [107]
Set components equal:
t = 8-s \\  5-t = s-3 \\  48 t^2 = s^2

From this we find:
t = 8-s \\  s =  4 \sqrt{3} t

Substitute and solve system:
t = \frac{8}{1+4 \sqrt{3}} = 1.009  \\ \\  s = 8-t = 8 - 1.009 = 6.991

The point where they intersect is:
(1.009, 5-1.009, 48(1.009)^2)
