Answer:
59 yards x 99 yards
Step-by-step explanation:
Soccer fields are rectangular. If the width is W and the length is L:
316 = 2W + 2L
5841 = WL
We have two equations and two variables. Start by solving for one of the variables in the first equation:
316 = 2W + 2L
158 = W + L
W = 158 − L
Substitute into the second equation
5841 = (158 − L) L
5841 = 158 L − L²
L² − 158 L + 5841 = 0
Factor (or use quadratic formula):
(L − 59) (L − 99) = 0
L = 59 or 99
Find W:
W = 99 or 59
Therefore, the dimensions of the soccer field are 59 yards by 99 yards.
789.652 rounded to the nearest tenth would be C. 789.7
$25 x 5 weeks = $125
$125 in 5 weeks + $120 = $245
In 5 weeks he will have $245 saved
