Answer 1

4.5cm^2

Explanation:

Find area of a square 3*3=9

Half of a square is 9/2=4.5

Answer 2

• 4.5 cm²

`\:`

Explanation:

It is given that, the height of a triangle is 3cm, and its base is 3cm and we are to find the area of triangle.

`\:`

To find the area of the triangle, we have to know this formula :

`\\ {\longrightarrow \pmb{\frak {\qquad Area_((Triangle)) = \: (1)/(2) * Base * Height \:}}} \\ \\`

Now, substituting the values in the formula :

`{\longrightarrow \pmb{\sf {\qquad Area_((Triangle)) = \: (1)/(2) * 3 * 3 \:}}} \\ \\`

`{\longrightarrow \pmb{\sf {\qquad Area_((Triangle)) = \: (1)/(2) * 9 \:}}} \\ \\`

`{\longrightarrow \pmb{\sf {\qquad Area_((Triangle)) = \: (9)/(2) \:}}} \\ \\`

`{\longrightarrow \pmb{\frak {\qquad Area_((Triangle)) = \: 4.5 \:}}} \\ \\`

Therefore,

• The area of the triangle is 4.5 cm² .
