Solution Steps

00:06 Let's find the area of the triangle!
00:09 We use the formula for a triangle's area.
00:12 It's base times height, divided by two.
00:17 Now, plug in the given numbers and calculate.
00:21 And there you have it, our area solution!

Step-by-Step Solution

To solve this problem, we will follow these steps:

  • Step 1: Identify the relevant sides based on problem context
  • Step 2: Apply the standard triangle area formula
  • Step 3: Calculate the area based on the known values for base and height

Let's work through each step in detail:

Step 1: We are seeking to calculate the area of the triangle. We identified that the line segment of 4 units represents the height, and the base is 7 units.

Step 2: We will apply the formula for the area of a right triangle: Area=12×base×height \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} .

Step 3: Plug the values we have: Area=12×7×4=12×28=14 \text{Area} = \frac{1}{2} \times 7 \times 4 = \frac{1}{2} \times 28 = 14 .

Thus, the area of the triangle is 14 14 square units.
