Question

what is the missing length?
6 mm
p
area = 30 mm²
p = millimeters

Explanation:

Step1: Recall the formula for the area of a rectangle

The area formula for a rectangle is \( A = \text{length}\times\text{width}\). Here, \(A = 30\space mm^{2}\), width \(w = 6\space mm\), and length \(l=p\). So, \(A=p\times w\).

Step2: Solve for \(p\)

Rearrange the formula \(p=\frac{A}{w}\). Substitute \(A = 30\) and \(w = 6\) into the formula: \(p=\frac{30}{6}\).

Answer:

\(5\)
