- The length of the door sign is 7 inches.
- Its area is 25 square inches.
We know that the area of a rectangle is
[tex]A= w \times l[/tex]
Where [tex]w[/tex] is width and [tex]l[/tex] is length.
We know by given that [tex]l= 7 \ in[/tex] and [tex]A= 25 \ in^{2}[/tex], replacing these values and solving for [tex]w[/tex], we have
[tex]25=7w[/tex] (this is the equation used to solve the problem).
[tex]w=\frac{25}{7} \approx 3.6 \ in[/tex]
Answer:
The equation is Area = length × width.
The width is approximately 3.57 inches.
Step-by-step explanation:
Door sign length, l = 7 inches
Area, A = 25 square inches
Width (w) is unknow.
Since the area is the product of the length and the width,
A = l×w
25 = 7×w
Dividing both sides by 7
w = 25/7
≈ 3.57 inches
