Question

6.9 in, 2.4 in (dimensions of a rectangular - shaped figure with square notches)

Explanation:

Step1: Identify the shape as a rectangle

The figure, despite the cut - out squares, has the same perimeter as a rectangle with length \( l = 6.9\) in and width \( w = 2.4\) in. The formula for the perimeter of a rectangle is \( P=2\times(l + w)\).

Step2: Substitute the values into the formula

Substitute \( l = 6.9\) and \( w = 2.4\) into the formula:
\(P = 2\times(6.9+2.4)\)
First, calculate the sum inside the parentheses: \(6.9 + 2.4=9.3\)
Then, multiply by 2: \(2\times9.3 = 18.6\)

Answer:

The perimeter of the figure is \(18.6\) inches.
