Question

BEED URGENT HELPPP!

(please help me answer these 3 questions, picture attached)


Questions:

1. what is the area of the whole rectangle?
( area = length * width )

2. what is the area of the shaded rectangle?

3. what is the area of the unshaded part of the rectangle? (area of the whole rectangle - area of the shaded part)

Answer 1

Answer: See below

Explanation:

1) For the first question, we have to multiply the width by the length to find the area of the whole rectangle:

(4x-4)(x+1)= 4x^2 -4

2) For the second question, we have to multiply the width by the length to find the area of the shaded area in the rectangle:

(2x+2)(x-1)= 2x^2-2

3) The total area of the unshaded part of the whole triangle equals the area of the whole rectangle minus the shaded area:

4x^2-4 - 2x^2 -2 = 2x^2 - 6
