Answer:
This is going to be really long so sorry in advance :)). So i split the shape into two (so straight down).This therefore allows me to calculate the areas of both rectangles and add them together - (to give total area)
Area of A x(x^2-6)
=x^3-6x
Area of B
=(2x^3-5x^2-12x+14) (5x-14)
10x^4-28x^3-25^3-70x^2-60x^2+168x+70x-196
simplified: 10x^4-53^3-130x^2+238x-196
so add both areas to give total are:
=(x^3-6x) +(10x^4-53x^3-130x^2+238x-196)
=10x^4-52x^3-130x^2+232x-196
Thats it hope it helps :)
