A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. Since the opposite sides are equal and parallel, a rectangle, therefore, it can also be termed as a parallelogram.

Answer:
A = 4 * 2 1/2
A = 4*5/2
Step-by-step explanation:
A = l*w
A = 4 * 2 1/2
Another way to write 2 1/2 is as an improper fraction
A = 4 * (2*2+1)/5
A = 4*5/2

To find area simply multiply Lenght times Width
x2 + 6x + 6 = 0
Answer:
The solution of x^2 + 6x + 6 is x = -1.2679 or -4.7320
Solution:
A two degree polynomial equation is given in the question.
We have been asked to solve it to find the value of ‘x’.
The given equation is:
There are two ways to solve this equation.
We can either factorise it or use the quadratic equation formula. For factorising it, it has to satisfy certain conditions.
The condition is should be a perfect square otherwise the equation is not factorable.
a=1,b=6,c=6
On substituting the values of a,b and c, we get:
Which is not a perfect square.
Hence we have to use the quadratic equation is
By substituting the values of a,b and in the quadratic equations. We get;
The two roots of x are:
On solving both the equations we will get the roots of the given equation, which are:
x = -1.2679 or -4.7320
Answer:
-1.2679 or -4.7320
