How to solve a conpostite figure

1 answer:

3 0

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

We are interested in the dimensions of a certain square. A rectangle has a length of 5 units more than the side of the square an

JulijaS [17]

Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2

and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 = $( x^{2} +5x)/2$ <- equation1
Area of square = Side* Side= x*x = $x^{2}$ <- equation2

As per given data, Equation1 and equation 2 are equal
so
$( x^{2} +5x)/2$ = tex] x^{2} [/tex]
$x^{2} +5x = 2 x^{2}$
$2 x^{2} - x^{2} = 5x$
$x^{2} = 5x$
x = 5

So the side of square = 5 units

For Square, both dimensions are equal.
