Can a triangle have two 30 degree angles?

Answer and Explanation:

Since the product of two quantities is commutative, we can assume the length to be 5 c m centimeters and the width to be 8 c m centimeters. Use the formula Area = Length × Width to get the rectangle's area. Hence, the area of the given rectangle is 40 square centimeters.

Definition of area in math

Area in math is about counting squares. When we define area, it means how many square units fit inside a shape or figure. If you picture a square 3O units long on each side, the area is 9 square units. This is because 9 squares, each 1 unit by 1 unit, can fit inside.

Perimeter is the length, the linear measurement around a shape or structure – a room or an entire building. Perimeter can be used to estimate mouldings, edgings, or other basic building or finish materials. Perimeter is equal to the sum of the sides. For a square this would be equal to four times one Side.

What is the value of pi? The value of pi is approximately 3.14, or 22/7. To 39 decimal places, pi is 3.141592653589793238462643383279502884197. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers.

What is the 45 45 90 rule?

Radius: the distance between any point on the circle and the center of the circle. It is equal to half the length of the diameter.

How many radians is a circle?

This is because one definition of a circle is all points in a plane the are a given distance (the radius) from a given point (the center). In your case, radius 1 means the distance from the center to the circumference is 1 (inch, centimeter, foot, yard, etc.).
