The side of the square is 5 cm. The sides of the rectangle are 4 cm and 7 cm. Whose area is larger and by how much.

1. Find the area of a square, for this we square the length of its side.

52 = 25 (cm2) square area.

2. Find the area of the rectangle for this, multiply the lengths of the sides of this rectangle.

4 * 7 = 28 (cm2) area of the rectangle.

3. Compare the areas of a rectangle and a square.

28> 25, which means the area of the rectangle is larger.

4. Find how much the area of the rectangle is larger than the area of the square, for which we subtract the area of the square from the area of the rectangle.

28 – 25 = 3 (cm2) is that much larger area of the rectangle.

Answer: 3 cm2.
