Problem 3. Finding the Dimensions of a Rectangle

SOLID MENSURATION PROBLEMS



     3.   A garden plot is to contain 200 sq. ft. If its length is to be twice its width, what should its                  dimensions be?
Let x be the Width and 2x be the Length.
x = Width
2x = Length

The area of the rectangle is L x W so

Now we got the value of the width which is 10 ft. We will substitute the value of x to the equation of the length.

The dimensions of the garden plot is :
                            20 ft. x 10 ft.



Problem 2. Finding the Area of the Largest Circle in a Square and Material Wasted

SOLID MENSURATION PROBLEMS

     2.   Find the area of the largest circle which can be cut from a square of edge 4 in. 
           What is the area of the material wasted

First we will find the area of the square.


The center of the square is also the center of the circle and if the edge of the square is 4 in. This means that the radius of the circle is 2 in. We can now find the area of the largest circle.

To find the material wasted we will subtract the Area of the square with the area of the circle.





Problem 1. Finding the Area of a Rectangle

SOLID MENSURATION PROBLEMS



  1. A window glass is 4 ft. and 2 in. by 2 ft. and 10 in. Find its Area.    

First we need to convert ft. units to in. units.
                      

And then add the converted unit.
 

Now we get the right magnitude of the sides we can now find the area of the window.
