Introduction to solving online geometry practice:
Geometry is a part of math which involves the study of shapes, lines, angles, dimensions, etc. it plays vital role real time application like elevation, projection. Learning geometry provides many foundational skills and helps to build the thinking skills of logic, deductive reasoning, and analytical reasoning. Flat shapes like lines, circles and triangles are called the Plane Geometry. Solid (3-dimensional) shapes like spheres and cubes are called Solid geometry. In this article we shall discuss about solving geometry practice problems online. Please express your views of this topic Gaussian Elimination Calculator by commenting on blog.
Solving Online Geometry Practice - Sample Problems
Example 1:
The perimeter of a rectangle is 800 meters and its length L is 3 times its width W. Find W and L, and the area of the rectangle.
Solution:
Perimeter of rectangle=2L+2W,
2 L + 2 W = 800
We now rewrite the statement. Its length L is 3 times its width into a mathematical equation as follows:
L = 3 W
We have to substitute L =3W in the equation 2 L + 2 W = 800
2(3 W) + 2 W = 800
8 W = 800
W =100 meters
Use the equation L = 3 W to find L.
L = 3 W = 225 meters
Use the formula of the area.
Area = L x W = 225 * 100 = 22500 meters 2.
So, the area of the rectangle=22500 meters 2.

Q 1) A perimeter of the triangle is 50cm. If 2 of its sides are equal and also the third side is 5cm more than the equal sides, find the length of the third side?
Solution:
Let x = length of the equal side.
Third side=5 more than the equal side=x+5
So, the three sides are x, x and x+5.
P = sum of the three sides
x+ x+(x+5) =50
Combine like terms
3 x + 5=50
3x = 50 – 5
3x = 45
x =15cm (equal sides)
Length of the third side=x+5=15+5=20cm
The length of third side is 20cm.
Q 2) A circle has an area of 100pi square units. What is the length of the circle's diameter and circumference?
Solution:
Area of the circle
A = (pi)*r^2
100pi = (pi)*r^2
(100pi) / pi = [(pi)*r^2] / pi
100= r^2
10 = r
So, the radius=10units
Diameter=2(radius) =20 units
Circumference= (pi)*d
=20pi units (or)
Substitute the value of pi=3.14
=62.8units
Circumference=20pi units (or) 62.8 units.
