How do you find an expression that represents the area of a triangle?

How do you find an expression that represents the area of a rectangle?

I just need examples..

surely your text explains that the area of a

rectangle is height times width
triangle is 1/2 times height times width

a web search will provide copious examples and explanations

To find an expression that represents the area of a triangle, you can use the formula:

Area = (Base x Height) / 2

Here's an example:
If the base of a triangle is b units and the height is h units, the expression for the area of the triangle would be (b * h) / 2.

To find an expression that represents the area of a rectangle, you can use the formula:

Area = Length x Width

Here's an example:
If the length of a rectangle is l units and the width is w units, the expression for the area of the rectangle would be l * w.

To find an expression that represents the area of a triangle, you can use the formula A = 1/2 * b * h, where A represents the area, b represents the base length, and h represents the height. Let's say you have a triangle with a base length of 4 units and a height of 6 units. To find the area, you can substitute these values into the formula:

A = 1/2 * 4 * 6

Simplifying, we get:

A = 12 square units

So, the expression representing the area of this triangle is A = 12.

Now, let's move on to finding an expression for the area of a rectangle. The formula to calculate the area of a rectangle is A = l * w, where A represents the area, l represents the length, and w represents the width. Consider a rectangle with a length of 5 units and a width of 3 units. To find the area, substitute these values into the formula:

A = 5 * 3

Simplifying, we find:

A = 15 square units

Therefore, the expression representing the area of this rectangle is A = 15.
