Answer:
l = 9 inches and b = 6 inches.
Step-by-step explanation:
Given that,
The perimeter of a rectangular price tag, P = 30 cm
The area of rectangular price tag, A = 54
We need to find the dimensions of the price tag.
The area of rectangle is given by :
A = lb
So,
54=lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
So,
30=2(l+b)
15=(l+b) ...(2)
We need to solve equation (1) and (2) such that,
l = 9 inches and b = 6 inches.
