These squares and rectangles have length and width measurements with decimals; can young geometers determine the exact perimeter of each? Using a step-by-step example as guidance, they show work to find the perimeter of each of these shapes. The units are already included in the answers here, but you could cover them up before copying to encourage kids to remember this step. All decimals in the measurements are to the tenths place. They will probably need to use another sheet of paper to show work, as there isn't much room.
