Answer 1

A contractor is putting in a wall in an office building to partition the room into two smaller rooms. The image above shows a 2-dimensional representation of a wall with a cut-out for a door.

Create the expression that represents the area of the wall space only using the dimensions shown above. Show your work.
The contractor is trying to design a scale model of the wall to show the buildings manager. To create this scale, he will have to divide the the area of the wall as calculated in Part A by 4xy4. With the polynomial in standard form, divide the first term only by 4xy4. Then divide the second term only by 4xy4. Show your work for the division of each term by 4xy4 separately.
If a window with the area of 12xy4 was placed on this wall, what would be the new area of the wall space left? You must show all work and calculations to receive credit.

Answer 2

Alright...so as you know the area would be Length x Width...

But we have a gap in the wall....

So the Area of the WHOLE thing...will be the WHOLE area - That Gap...
