Question

Please Help! :)

The height of a rectangle is 3 units less than twice the width.

A) If the width of the rectangle is represented by the variable w, write an expression for the height in terms of w.

B) Write an equation for the areas of the rectangle in terms of w.

Answer 1

H = 2W - 3 <== height in terms of W

A = H * W
A / H = W <== area in terms of W

Answer 2

Answer: A)h = 2w-3

B)A = 2w²-3w

Explanation:

Since we have given that

Let the width of rectangle be 'w'.

Let the height of rectangle be 'h'

According to question, we have

The height of a rectangle is 3 units less than twice the width.

A) So, our equation becomes,

h = 2w-3

As we know that

Area of rectangle = height × width

A = h×w= (2w-3)w = 2w²-3w.

Hence, A = 2w²-3w
