Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²

<u><em>Answer:</em></u>
<u>The simplest form would be:</u>
8c² - 1.5d
<u><em>Explanation:</em></u>
To simplify an expression, we need to <u>gather the like terms</u>.
Like terms are the ones having the same variable raised to the same power
<u>In the given expression:</u>
6c² + 2.5d - d + 2c² - 3d
We have terms having c² and terms having d.
<u>Therefore, we would gather them as follows:</u>
6c² + 2.5d - d + 2c² - 3d
(6+2)c² + (2.5-1-3)d
8c² - 1.5d ......................> This is the simplest form
Hope this helps :)
