The video tutorial covers solving word problems involving rectangles using algebra. It begins with a problem where the length of a rectangle is 1 cm less than twice its width, and the area is 45 square cm. The solution involves setting up a quadratic equation and factoring it to find the dimensions. The second problem involves a rectangle with an area of 33 square meters, where the length is 2 meters more than three times the width. Again, a quadratic equation is used to find the dimensions. The tutorial emphasizes understanding the relationship between length, width, and area, and solving quadratic equations through factoring.
