Area is squared so divide 56/6 gives you 9.3 round down so length of base is 9 m.
Answer:
Step-by-step explanation:
You have two methods to expand this binomial.
Method 1
If you have the expression:
You can write the expression it in the following way:
Then, apply the distributive property:
Simplify the expression:

Method 2
For any expression of the form:
Its expanded form will be:
If
Well the question doesnt show any number for a side or anything but we can solve this with algebra if we say that a side from one base to next has a length of x. so we know each side has length x and that the shape they make is square. This means we are only searching for the diagonal of a square.
remember that a diagonal forms and isoscoles right triangle with the 2 sides being equal and the diagonal as the hypotenuse. Using the pythagoream theorem we can say that
a^2 + b^2 = c^2
we said all side lengths are x so we can put x in for a and b and get
x^2 + x^2 = c^2
2x^2 = c^2
c = x * squareroot(2)
that is the basic fundamental answer that will always work when working with diagonals of squares.
so if the length between bases is 90 ft, we could plug this in and get
c = 90 ft * squareroot(2)
c = 127.28 ft
