2. Making Equations (2) Algebra

3. 5 x + 7 Area = 53cm 2 The area of a rectangle. In each of the examples below, the area of the rectangle is given. Make an equation and solve it to find x. Hence state the lengths of the sides of the rectangles. 3 2x + 1 Area = 19cm 2 4 x + 5 Area = 27cm 2 2 3x + 2 Area = 17cm 2

4. Make an equation and solve it to find x. Hence state the lengths of the sides of the rectangles. 6 2x - 5 Area = 67cm 2 x + 1 7 Area = 57cm 2 8 2x + 3 Area = 86cm 2 4 3x - 1 Area = 35cm 2
