Q. Triangle\newlineb=30 mh=15.6 m \begin{array}{l} b=30 \mathrm{~m} \\ h=15.6 \mathrm{~m} \end{array}
  1. Recall Triangle Area Formula: Recall the formula for the area of a triangle.\newlineThe area AA of a triangle is given by the formula A=base×height2A = \frac{\text{base} \times \text{height}}{2}.
  2. Substitute Given Values: Substitute the given values into the formula.\newlineHere, the base bb is 30 m30\,\text{m}, and the height hh is 15.6 m15.6\,\text{m}. So, A=30 m×15.6 m2A = \frac{30\,\text{m} \times 15.6\,\text{m}}{2}.
  3. Perform Multiplication: Perform the multiplication.\newlineMultiply the base and height: 30 m×15.6 m=468 m230\,\text{m} \times 15.6\,\text{m} = 468\,\text{m}^2.
  4. Divide to Find Area: Divide by 22 to find the area.\newlineNow divide the result by 22 to get the area: 468 m2/2=234 m2468\,\text{m}^2 / 2 = 234\,\text{m}^2.
