To find the lengths of the sides of each rectangle, we calculate the distances between the points. For rectangle \( EFGH \): - The length (EF or HG) is the difference in the y-coordinates: \(8 - 6 = 2\). - The width (EH or FG) is the difference in the x-coordinates: \(7 - 3 = 4\). - The perimeter is calculated by adding all sides: \(2(2 + 4) = 12\). For rectangle \( IJKL \): - The length (IJ or KL) is the difference in the y-coordinates: \(9 - 4 = 5\). - The width (IL or JK) is the difference in the x-coordinates: \(8 - 1 = 7\). - The perimeter is calculated as: \(2(5 + 7) = 24\). So, the perimeters are 12 for rectangle EFGH and 24 for rectangle IJKL!
