Step-by-step solution

To solve this problem for the area of the trapezoid, we'll follow these steps:

  • Identify the given dimensions: two parallel sides (bases) and the height.
  • Apply the formula for the area of a trapezoid.
  • Compute the necessary calculations.

Let's proceed with the calculations:
Step 1: The lengths of the two bases are Base1=9.6\text{Base}_1 = 9.6 and Base2=13\text{Base}_2 = 13.
Step 2: The height between these bases is 5.85.8 units.
Step 3: Use the formula for the area of a trapezoid:
Area=12×(Base1+Base2)×Height \text{Area} = \frac{1}{2} \times (\text{Base}_1 + \text{Base}_2) \times \text{Height} Plug in the values:
Area=12×(9.6+13)×5.8 \text{Area} = \frac{1}{2} \times (9.6 + 13) \times 5.8 Calculate the sum of the bases:
9.6+13=22.6 9.6 + 13 = 22.6 Now perform the multiplication and division:
Area=12×22.6×5.8 \text{Area} = \frac{1}{2} \times 22.6 \times 5.8 Area=11.3×5.8 \text{Area} = 11.3 \times 5.8 Area=65.54 \text{Area} = 65.54

Therefore, the area of the trapezoid is 65.5465.54 square units.

65.54

Key Points to Remember

Essential concepts to master this topic
  • Formula: Area = 12×(b1+b2)×h \frac{1}{2} \times (b_1 + b_2) \times h
  • Technique: Add bases first: 9.6 + 13 = 22.6, then multiply by height
  • Check: Units should be square units and answer makes sense geometrically ✓

Common Mistakes

Avoid these frequent errors
  • Using wrong formula or forgetting the 1/2
    Don't just multiply base times height like a rectangle = 131.08 wrong answer! This ignores that trapezoids have two different parallel sides, not four equal sides. Always use the trapezoid formula with 1/2 and add both bases together.

FAQ

Everything you need to know about this question

Which sides are the bases in a trapezoid?

+

The bases are the parallel sides! In this problem, that's the top side (9.6) and bottom side (13). The height is always perpendicular to these parallel sides.

Why do we multiply by 1/2 in the trapezoid formula?

+

Think of a trapezoid as the average of two rectangles! The 12 \frac{1}{2} finds the average width: 9.6+132=11.3 \frac{9.6 + 13}{2} = 11.3 , then multiply by height.

What if I can't tell which measurement is the height?

+

The height is always the perpendicular distance between the parallel sides. Look for the measurement that connects the two bases at a right angle (90°).

Do I need to worry about decimal places in my answer?

+

Keep all decimal places from your calculation unless the problem asks you to round. In this case, 65.54 is the exact answer from our multiplication.

Can I use this formula for any trapezoid?

+

Yes! This formula works for all trapezoids - whether they lean left, right, or are perfectly upright. Just identify the two parallel sides and the height between them.
