Answer:
- the shape is a trapezoid
- use the area formula
- 48783 mm²
Explanation:
The top and bottom edges are parallel, and the shape has 4 sides. That means it is a trapezoid. The area can be found using the formula for the area of a trapezoid:
A = 1/2(b1 +b2)h
A = 1/2(85 mm + 218 mm)(322 mm) = 1/2(303)(322) mm² = 48783 mm²
