Geometry Practice Problems

Introduction for learning geometry problem answers:

The subdivision  of mathematics concerned with the properties of lines, curves and surfaces usually divided into pure, algebraic and differential geometry in accordance with mathematical techniques utilized.  The figures of two dimensions is called planes. learning Geometry problem answers is a module of math which involves about the study of shapes, lines, angles, dimensions, relative position of figures etc. it plays vital role in real time application like elevation, projection. Learning geometry problems answers provides many foundational skills and helps to build the thinking skills of logic, deductive reasoning, and analytical reasoning.Let us learn geometry problem answers. I like to share this What are Similar Triangles with you all through my article.


learning geometry problem answers:


A triangle has a perimeter of 56. If 2 of its sides are equal,then the  third side is 5 more than the equal sides, what is the length of the third side?

Solution:

Let y = length of the equal side
perimeter of triangle.

Perimeter of a  triangle = sum of all the 3 sides.
Plug in values of question.
56 = y + y + y + 5

Combine like terms
56 = 3y + 5

3y = 56 – 5
3y = 51
y =17

Note: the third side is 5 more than the equal sides.

So, the length of third side = 17 + 5 =22

Answer: The length of third side is 22.

Understanding tricky math problems for kids is always challenging for me but thanks to all math help websites to help me out.

The perimeter of a rectangle is 400 meters and its length is 3 times its width W. Find Width and Length, and the area of the rectangle.

Solution:

Use the perimeter formula to write.

2 L + 2 W = 400
"its length is 3 times its width W" into a mathematical equation as follows:

L = 3 W
We substitute L = 3 W in the equation 2 L + 2 W = 400.

2(3 W) + 2 W = 320
Expand and group like terms.

8 W = 400
Solve for W.

W = 50 meters
Use the equation L = 3 W to find L.

L = 3 W = 150 meters
Use the formula of the area.

Area = L x W = 150 * 50 = 7500 meters 2.
