Question

the width of a rectangle is 4 inches shorter than its length. if the length of the rectangle is 7 inches, write and solve an addition equation to find the width of the rectangle.
choose the correct answer.
a. 4 = w + 7
b. 7 = w + 4
c. w = 7 + 4
d. 7 = w - 4

Explanation:

Step1: Analyze the relationship between length and width

Let the width be \(w\). Given that the width is 4 inches shorter than the length. So, length \(=\) width \( + 4\).

Step2: Substitute the value of length

Since the length is 7 inches, the equation is \(7=w + 4\).

Step3: Solve the equation for \(w\)

Subtract 4 from both sides of the equation \(7=w + 4\).
\(7-4=w+4 - 4\)
\(w = 3\)

Answer:

B. \(7 = w+4\)
