Question

Find the area of the triangle. Single choice.

(10 Points)

48 square units
96 square units
20 square units
28 square units

Answer 1

48 square units

Explanation:

The area of a triangle is calculated by multiplying height to the base and that divided by two

The height of the given triangle is 8 units and the base is 12 units

8×12÷2 = 48

Answer 2

Answer:-

`\pink{\bigstar}` Area of the triangle is

• Knowledge Required:-

✯ In order to find the area of a triangle we must know about 2 parameters i.e, height and base of the traingle.

✯ We need to count the number of grids present inside the triangle or forming the triangle vertically to know about the height of the triangle. Similarly, counting the grids horizontally will give us the base of the triangle.

• Solution:-

Following the above steps we get to know the required parameters.

• Height = 8 units

• Base = 12 units

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Now moving on, there is a formula to find out the area of a triangle.

`\pink{\bigstar}`
`\large\underline{\boxed{\bf\green{Area_((triangle)) = (1)/(2) * b * h}}}`

where,

• b = base of the triangle

• h = height of the triangle

• Substituting in the Formula:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪
`\sf Area_((triangle)) = (1)/(2) * 12 * 8`

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪
`\sf Area_((triangle)) = (1)/(2) * 96`

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★
`\bold\red{Area_((triangle)) = 48 \: square \: units}`

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the Area of the given triangle is 48 square units.
