Question

the length of the batter's box on a softball field is 1 ft less than twice the width. the area of the batter's box is 15 ft^2. Find the length and width of the batter's box. Can the formula for a rectangle apply to this?

Answer 1

A=L*W
L= 2W-1
15 = (2W-1)*W
15= 2W^2-W
0= 2W^2 -W-15
(2W+5)(W-3)
W=-5/2 or W=3 the width can not negative than
W=3 is solution
L= (2*3)-1
L= 5
check:
A=3*5
A=15
