Question

look at this rectangle. find the value of t.
11 mm
perimeter = 50 millimeters
t = millimeters

Explanation:

Step1: Recall perimeter formula for rectangle

The perimeter \( P \) of a rectangle is given by \( P = 2\times(\text{length} + \text{width}) \). Here, length is \( 11 \) mm, width is \( t \) mm, and \( P = 50 \) mm. So, \( 50 = 2\times(11 + t) \).

Step2: Solve the equation for \( t \)

First, divide both sides of the equation by \( 2 \): \( \frac{50}{2}=11 + t \), which simplifies to \( 25 = 11 + t \). Then, subtract \( 11 \) from both sides: \( t = 25 - 11 = 14 \).

Answer:

14
