Answer:

30m²

Step-by-step explanation:

Let's derive the area of a triangle

We know the formula for the area of a rectangle:


  • \text{A = l * w}

Here, we can see that the area of the triangle is the rectangle's are divided by 2, or half of the rectangle's area.

Here's the formula for the area of a triangle:


  • \text{A} = (1)/(2)\text{b * h}

B is the base, the same as the length

H is the height, the same as the width

Solve:


  • \text{A} = (1)/(2)\text{b * h}

  • \text{A} = (1)/(2)(10 * 6)

  • \text{A} = \frac12(60)

  • \text{A} = 30\\

The units is m * m, or m²

Area = 30m²

Answer:

area of shaded: 30 m²

Step-by-step explanation:

  • Here triangle is inscribed in a rectangle.
  • Rectangle area: Length * Width
  • Triangle area: (1/2) * base * height
  • The triangle here is shaded.

Steps:

Rectangle area: 6 * 10 = 60 m²

Triangle area: (1/2) * 6 * 10 = 30 m² .......this is the area of shaded.
