Answer:
352 m²
Step-by-step explanation:
We assume you have the figure shown below. Its area can be computed a couple of ways:
1. Area of Rectangle + Area of Triangle
The area of the rectangle is the product of its dimensions:
18 m × 16 m = 288 m²
The area of the triangle is half the product of its base and height:
(1/2)(8 m)(16 m) = 64 m²
Then the area of the trapezoid is ...
288 m² +64 m² = 352 m²
__
2. Area of Trapezoid
The long base of the trapezoid has length 18 m + 8 m = 26 m. This can be used in the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
= (1/2)(26 m +18 m)(16 m) = 352 m²
The area of the figure is 352 m².
