We can find the area by counting the squares within the rectangle. There are squares.

We can also multiply the length and the width to find the area.

*Area is the number of square units inside a shape, which is why area is always written with square units.

When we count the squares, there are squares that make up the rectangle.

The formula for perimeter of a rectangle is

To solve for the perimeter we can plug our known values into the equation.

The formula to find area is . We are given the length and the width from the problem, so we can plug those values into our equation and solve.

*Area is the number of square units inside a shape, which is why area is always written with square units.

To solve, simply use the formula for the perimeter of an equilateral triangle. Thus,

Remember, the special property of an equilateral triangle is that all of its sides are the same length so, you can either add the side length 3 times or multiply it by 3.
