![]() ![]() ![]() We’ll simply multiply the length by the width, just like the area of the rectangle formula. Area the 2 dimensional space surrounded by the sides of the shape. (i) A polygon having all sides equal and all angles equal is called a regular polygon. For the above circle, the first moment of area about the -axis is given by, Qx Q x A x As, area of the circle, A. Perimeter is the length and width around the object the sum of all outer sides. ![]() Step 3: Let’s check to verify if both dimensions will give us the pool’s area. The first moment of area for circle, hollow circle, and rectangle shape is given below:- 1 For circle:- The below figure shows the circle with the centroid located at a distance of (x, y) from the origin of the axis.Step 2: Now that we know the measurement of the pool’s width or the value of the variable W, we can easily find the length.The area of a rectangle is the amount of two-dimensional space inside the boundary on rectangle. If we are given the area and one side, we can work. All four interior angles of a rectangle are 90.(right angles). Just like in our previous example, we will find the measurement of the rectangle’s width by substituting the given value of the area and length into the area of rectangle formula, then solve for the width ( W). To determine the area of a rectangle, we must multiply the length and width. ![]()
