Answer:

302 m²

Explanation:

You want the area of the figure composed of a triangle and rectangle.

Area

The formulas for the areas of the parts are given in the problem statement.

Triangle

The base length of the triangle is (18 m - 5m - 5 m) = 8 m. Then its area is ...

A = 1/2bh

A = 1/2(8 m)(8 m) = 32 m²

Rectangle

The area of the rectangle is ...

A = LW

A = (18 m)(15 m) = 270 m²

Figure

The area of the figure is the sum of the areas of its parts:

A = (triangle area) + (rectangle area)

A = 32 m² +270 m² = 302 m²

The area of the figure is 302 m².
