Answer 1

Формула а+б разделить на 2 и умножить на высоту

Answer 2

Problem Analysis

We are given a trapezoid with a smaller side length of 5 cm and the lengths of its bases as 7 cm and 13 cm. We need to find the area of the trapezoid.

Solution

The formula to find the area of a trapezoid is given by:

Area = (a + b) * h / 2

Where: - a and b are the lengths of the bases of the trapezoid - h is the height of the trapezoid

In this case, the lengths of the bases are 7 cm and 13 cm, and the height is not given. However, we can use the smaller side length of 5 cm as the height of the trapezoid.

Substituting the values into the formula, we get:

Area = (7 + 13) * 5 / 2

Simplifying the expression, we have:

Area = 20 * 5 / 2

Calculating the result, we find:

Area = 50 cm²

Therefore, the area of the trapezoid is 50 cm².

Answer

The area of the trapezoid is 50 cm².
