To find the area of a triangle, you can use the formula:

\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]

For the triangle with a base of 8 inches and a height of 4 inches:

\[ \text{Area} = \frac{1}{2} \times 8 , \text{in} \times 4 , \text{in} = \frac{1}{2} \times 32 , \text{sq. in} = 16 , \text{sq. in} \]

So the area of the triangle is 16 sq. in.


For the rectangle, the area can be calculated using the formula:

\[ \text{Area} = \text{length} \times \text{width} \]

For the rectangle with a length of 10 m and a width of 5 m:

\[ \text{Area} = 10 , \text{m} \times 5 , \text{m} = 50 , \text{sq. m} \]

So the area of the rectangle is 50 sq. m.


Final Answers:

  1. Triangle area: 16 sq. in.
  2. Rectangle area: 50 sq. m.
