Answer:
The sticker is 8 millimeters x 6 millimeters
Step-by-step explanation:
A = Lw = 48
P = 2L + 2w = 28
Perimeter:
2L + 2w = 28
2 (L + w) = 28
L + w = 14
L = 14 - w
Subsitute Into Area:
A = Lw = 48
(14 - w)w = 48
14w - w² = 48
(subtract/add 14w - w² to both sides)
0 = w² - 14w + 48
Solve ^
= 8 and = 6
Typically the length is larger, so our answer is
The sticker is 8 millimeters x 6 millimeters
(hopefully this makes sense, have a nice day!)
