A rectangle has vertices at (−1, 6), (−1,−2), (3, 6), and (3,−2). Sara says the area of the rectangle is 16 square units and her work is shown. Sara’s Work Step 1: Base: absolute value of negative 1 plus absolute value of 3 is equal to 4 Step 2: Height: absolute value of 6 plus absolute value of negative 2 is equal to 4 Step 3: Area: 4 times 4 is equal to 16 square units Where, if at all, did Sara first make a mistake in finding the area of the rectangle?

Which rectangle has an area of 40 square units?

A rectangle has vertices at (−3, 2), (7, 2), (7,−5), and (−3,−5). Jordan says the area of the rectangle is 70 square units. Jordan’s Work Step 1: Base: absolute value of negative 3 plus absolute value of 7 is equal to 10 Step 2: Height: absolute value of negative 5 plus absolute value of 2 is equal to 7 Step 3: Area: 10 times 7 is equal to 70 square units Which is true of Jordan’s solution?

A rectangle has vertices at (−2, 11), (−2, 4), (6, 11), and (6, 4). Pablo says the area of the rectangle is 49 square units and his work is shown. Pablo’s Work Step 1: Base: absolute value of negative 2 plus absolute value of 6 is equal to 8 Step 2: Height: 11 minus 4 is equal to 7 Step 3: Area: 8 times 7 is equal to 49 square units Where, if at all, did Pablo first make a mistake finding the area of the rectangle?
