Chris and Oscar bought a new television for their mom. They want to be sure it will fit on the wall, so they need to calculate the perimeter of the television. Use the graph to help them calculate the perimeter of the television.
To calculate the perimeter of the television, we need to add up the lengths of all four sides.
Looking at the graph, we can see that the television is a rectangle with sides labeled as follows:
- Top side: 40 inches
- Bottom side: 40 inches
- Left side: 26 inches
- Right side: 26 inches
To calculate the perimeter, we add up all the sides:
Perimeter = Top side + Bottom side + Left side + Right side
Perimeter = 40 + 40 + 26 + 26
Perimeter = 132 inches
Therefore, the perimeter of the television is 132 inches. Chris and Oscar can use this measurement to ensure the television will fit on the wall.
