Use the coordinates to find the length of each side. Then find the perimeter of the rectangle. a. \( E(3,6), F(3,8), G(7,8), H(7,6) \) b. \( I(1,4), J(1,9), K(8,9), L(8,4) \)

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!
