If both the base and height of a triangle are made nine times as long, how many times the area of the original figure is the area of the new figure?

Answers

To start: A = 1/2bh
Now by increasing both the width and height by 9, you get: A = 1/2(9b)(9h) = 1/2(81)bh

You can see that the increase in area is 81 times the original.

What is a quadratic equation?

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The quadratic equation will be solved as follows:-

x² -10x + 25 = x² -5x - 5x + 25

                   =  x ( x- 5 ) - 5 ( x-5 )

                   =  ( x - 5 ) ( x - 5 )

The factors of the equation are 5 and 5.

Therefore the correct answer is option B which is the factors are (x-5)(x-5).
