Answer:

  • parallelogram: 80 mm²
  • triangle: 40 mm²

Explanation:

The formula for the area of a parallelogram is ...

A = bh

Here, the base is 8 mm and the height (perpendicular to the base) is 10 mm. Then the area is ...

A = (8 mm)(10 mm) = 80 mm² . . . . area of the parallelogram

__

As you can see from the problem setup, the area of the triangle is exactly half that: 80 mm²/2 = 40 mm² . . . . area of the triangle

_____

If you'd rather use the formula for the triangle area, you will see that you get the same result:

A = (1/2)bh

A = (1/2)(8 mm)(10 mm) = 1/2·80 mm² = 40 mm² . . . . area of the triangle
