  1. Perimeter of a Rectangle Word Problems

    The key to solving perimeter word problems is to know two things: 1) The formula of the perimeter of a rectangle. Perimeter of a Rectangle Formula: [latex]{\textbf{\textit{P = 2L + 2W}}}[/latex] Remember that the length (L) is the longest sideof the rectangle while the width (W) is the shortest side.

  2. Perimeter & area (video)

    Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy. Created by Sal Khan.

  9. Manipulating formulas: perimeter (video)

    Video transcript. We are told that the formula for finding the perimeter of a rectangle is P is equal to 2l plus 2w, where P is the perimeter, l is the length, and w is the width. And just to visualize what they're saying, and you might already be familiar with this, let me draw a rectangle. That looks like a rectangle.

  10. Perimeter

    P = a + b + c. Write the formula for finding the perimeter of any triangle. P = 19 m + 19 m + 19 m. Since the sides of the triangle are equal, we will simply add 19 three times. Alternatively, we can get the perimeter of an equilateral triangle by multiplying the measure of the side by 3. Hence, P = 3 x 19 mP = 57 m.

  25. Challenge problems: perimeter & area (video)

    So this inner pentagon has a perimeter 50, that is the sum of the 5 bases. So that right over here is 50, so the perimeter of the star is going to be 150 minus 50, or or 100. All we need is to get the perimeter of all triangles, subtracted out these bases which was the perimeter of the inner pentagon and we are done. Now lets do the next problem.
