Math Problem Statement

Calculate the area of this right-angled triangle. Give your answer to 1 d.p.

Solution

To calculate the area of the right-angled triangle in the image:

Formula:

The area of a triangle is calculated as: Area=12×base×height\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}

Given:

  • Base = 12m12 \, \text{m}
  • Height = 7m7 \, \text{m}

Substitution:

Area=12×12×7\text{Area} = \frac{1}{2} \times 12 \times 7

Area=12×84=42m2\text{Area} = \frac{1}{2} \times 84 = 42 \, \text{m}^2

Final Answer:

The area of the triangle is 42.0 m² (to 1 decimal place).
