The area of a rectangle is given by the formula: Area = length * width. The length is 5 - 1 = 4 and the width is 4 - 1 = 3. Thus, Area = 4 * 3 = 12.

The area of a square is given by the formula: A = side². Here, A = 7² = 49.

The area of a square is given by Area = side². The side length is 5 - 1 = 4, so Area = 4² = 16.

The area of a trapezoid is given by the formula: A = 0.5 * (base1 + base2) * height. Here, A = 0.5 * (6 + 10) * 4 = 0.5 * 16 * 4 = 32.

The circumference of a circle is given by the formula: C = 2πr. Here, r = 5, so C = 2π * 5 = 10π.

The length of a vertical line segment is the difference in the y-coordinates. Here, length = 7 - 3 = 4.

The perimeter of a triangle is the sum of the lengths of its sides. Here, Perimeter = 3 + 4 + 5 = 12.
