Find The Area Of The Polygon In Square Units. The Numbers Are 7, 13, 15, and 7

To find the area of the polygon, we need to know the shape of the polygon. Assuming that the polygon is a quadrilateral, we will first need to determine if it is a rectangle, square, parallelogram, trapezoid, or rhombus.

Given the side lengths are 7, 13, 15, and 7 units, we can calculate the area of the polygon as follows:

Using a formula for the area of a trapezoid:
Area = ((b1 + b2) * h) / 2

Where:
b1 = 7 units
b2 = 15 units
h = 13 units

Area = ((7 + 15) * 13) / 2
Area = (22 * 13) / 2
Area = 286 / 2
Area = 143 square units

Therefore, the area of the polygon described with side lengths 7, 13, 15, and 7 units is 143 square units.
