Determine the area of the shaded region labeled **A **in the figure below:

Correct! The area of region **A** is 5.

Sorry, the area of region **A** is 5. To determine the area, try dividing the region up into a rectangle and a triangle, and then calculate each area separately. The area of the rectangle is 4 and the area of the triangle is 1.

Determine the area of the shaded region labeled **A **in the figure below:

Correct! The area of region **A** is 300.

Sorry, the area of region **A** is 300. The area of triangle region **A** is ½ height times base, or 0.5 × 15× 40=300.

Determine the area of the shaded region labeled **A **in the figure below:

Correct! The area of region **A** is 8.

Sorry, the area of region **A** is 8. To determine the area try dividing the region up into a rectangle and a triangle, then calculate each area separately. The area of the rectangle is 6 and the area of the triangle is 2.

Determine the area of the shaded region labeled **A **in the figure below:

Correct! The area of region **A** is 4.

Sorry, the area of region **A** is 4. The area of triangle region **A** is ½ height times base, or 0.5 × 2 × 4=4.

Determine the area of the shaded region labeled **A **in the figure below:

Correct! The area of region **A** is 4.

Sorry, the area of region **A** is 4. The area of triangle region **A** is ½ height times base, or 0.5 × 2 × 4=4.

Determine the area of the shaded region labeled **A** in the figure below:

Correct! The area of region **A** is 10,000.

Sorry, the area of region **A** is 10,000. The area of triangle region **A** is ½ height times base, or 0.5 × 50 × 400=10,000.
