23 * 31 = 20 * 30 + 20 * 1 + 3 * 30 + 3 * 1 = 600 + 20 + 90 + 3 = 713.
To solve multiplication equations using models, you can represent the factors with visual aids like arrays or area models. For instance, if you want to solve (3 \times 4), you can create an array with 3 rows and 4 columns, visually showing 12 total units. Alternatively, an area model can be used to illustrate the product as the area of a rectangle with length 3 and width 4. These visual representations help in understanding the relationship between the factors and the product.
You multiply the length times the width using this formula:l x w=a (a=area)
easy
To solve an area without a given height, you can use other known dimensions or properties of the shape. For example, in the case of a triangle, if you know the lengths of all three sides, you can apply Heron's formula. For rectangles or squares, if you have the lengths of the sides, you can calculate the area directly using the formula length × width. In some cases, trigonometric relationships or coordinate geometry may also be utilized to find the area without directly using height.
Area can be measured in square inches.

The area of Saint-Solve is 5,840,000.0 square meters.
Set up the equation and solve using the formula for area of a circle: (pi = 3.14) a = P * r-squared (substitute with known numbers) 113.04 = 3.14 * r-squared (divide both sides by pi (3.14)) 36 = r-squared (find the square root of 36 to solve for the radius) 6 = r
Cylinders need a radius and a height and then u solve it by using the formula
To find the area, the formula is: pi*r2.Plug in the information: pi*(4)2.Solve: pi*16
you have to count the area around it!
