Answer :
The total length of Joe's shape will be the sum of these lengths, which is 12 + 9 + 9 = 30cm.
To find the total length of Joe's shape, we first need to determine the length of each part of the strips.
For the first strip, which is divided into three equal parts, each part will be 36/3 = 12cm long. For the second strip, which is divided into four equal parts, each part will be 36/4 = 9cm long.
To make the shape, Joe will need to use two strips. Let's assume that Joe places the strip with three equal parts horizontally and the strip with four equal parts vertically. He will then need to cut each strip into the appropriate lengths to create the shape.
To create the shape, Joe will need to use one 12cm length from the first strip and two 9cm lengths from the second strip. He will then need to connect these lengths together to create the shape.
These lengths will add up to a total length for Joe's shape of 12 + 9 + 9 = 30 cm.

The correct total length of Joe's shape is 39 centimeters.
Joe has two strips of card, each 36 centimeters long. One strip is divided into three equal parts, and the other strip is divided into four equal parts. To find the total length of Joe's shape, we add the lengths of the two strips.
For the first strip (divided into three equal parts), each part is [tex]\( \frac{36}{3} = 12 \)[/tex]
centimeters long.
For the second strip (divided into four equal parts), each part is [tex]\( \frac{36}{4} = 9 \)[/tex]
centimeters long.
If Joe uses the strips as shown in the figure, where he takes the second strip (divided into four equal parts) and uses three of those parts, the correct calculation as per fig would be
[tex]\[ \text{Total length} = 12 \, \text{(first strip)} + 9 + 9 + 9 \, \text{(three parts of the second strip)} \][/tex]
[tex]\[ \text{Total length} = 12 + 27 \][/tex]
[tex]\[ \text{Total length} = 39 \, \text{centimeters} \][/tex]
So, the correct total length of Joe's shape is 39 centimeters.
