#Formula for area of a rectangle how to
Have the base and the height, it's just going to be theīase times the height. This tutorial will show you how to find the area of a rectangle. The area of a parallelogram is just going to be, if you So the area of a parallelogram, let me make this looking more I just took this chunk ofĪrea that was over there, and I moved it to the right. So the area here is also the area here, is also base times height. The area of this parallelogram, or well it used to be this parallelogram, before I moved that triangleįrom the left to the right, is also going to be theīase times the height. That just by taking some of the area, by taking some of the area from the left and moving it to the right, I have reconstructed this rectangle so they actually have the same area. What just happened when I did that? Well notice it now looks just And what just happened? What just happened? Let me see if I can move Solution: As we know, the Area of a rectangle l × b Here the area is already given, so find the length of the rectangle. Using the Pythagorean theorem: w 2 + 24 2 26 2 w 2 + 576 676 w 2 100 w 10 The area of the rectangle is: A l×w 24×10 240. The diagonal of a rectangle divides it into two congruent right triangles. This area right over here and I'm going to move it Find out the length of the rectangle if the area is 96 cm 2 and the breadth is 16 cm. Since the area of a rectangle is a product of its length and width, we need to find the width. Of the parallelogram and I'm going to take Remember we're just thinking about how much space is inside So it's still the same parallelogram, but I'm just going to Little chunk right there, Actually let me do it a little bit better. So I'm going to take this, I'm going to take this Helps make up the parallelogram, and then move it to the right, and then we will see Going to take a chunk of area from the left-hand side,Īctually this triangle on the left-hand side that Well this isn't as obvious as if we're dealing with a rectangle.
When you have a parallelogram, you know its base and its height, what do we think its area is going to be? So at first it might seem
Perpendicularly straight down, you get to this side, that's going to be, that's going to be our height. Go from this side up here, and you were to go straight down. Length of these sides that at least the way I've drawn So when we talk about the height, we're not talking about the Its area is just going to be the base, is going to be the base times the height. With base length b and height length h, we know
