Math Problem Statement

Find the area of the triangle in the figure below. Show all work. (Base = 9.5m, Height = 8.7m)

Solution

The problem involves finding the area of the triangle shown in the image. Here's the solution:

Given Information:

  • Base (AC) = 9.5m9.5 \, \text{m}
  • Height (AB) = 8.7m8.7 \, \text{m}
  • The triangle is labeled as ABC\triangle ABC, with ABAB as the height perpendicular to ACAC, the base.

Formula for the area of a triangle:

Area=12×base×height\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}


Substituting the values:

Area=12×9.5m×8.7m\text{Area} = \frac{1}{2} \times 9.5 \, \text{m} \times 8.7 \, \text{m}

Step-by-Step Calculation:

Area=12×82.65m2\text{Area} = \frac{1}{2} \times 82.65 \, \text{m}^2 Area=41.325m2\text{Area} = 41.325 \, \text{m}^2


Final Answer:

A: 41.33m2(rounded to two decimal places)\text{A: } 41.33 \, \text{m}^2 \, (\text{rounded to two decimal places})
