Question

HELP, PLEASE!! I WILL 5 STAR!

Answer 1

Answer:

Length: 18 yd, Width: 5.5 yd

Step-by-step explanation:

w - width

2w + 7 - length

99 yd² - area of a rectangle

The formula of an area of a rectangle:

A = lw

l - length

w - width

Substiute:

w(2w + 7) = 99                use the distributive property

2w² + 7w = 99               subtract 99 from both sides

2w² + 7w - 99 = 0

2w² + 18x - 11x - 99 = 0

2w(w + 9) - 11(x + 9) = 0

(w + 9)(2w - 11) = 0 ⇔ w + 9 = 0 or 2w - 11 = 0

w + 9 = 0      subtract 9 from both sides

w = -9 < 0 !!!

2w - 11 = 0                add 11 to both sides

2w = 11         divide both sides by 2

w = 5.5 yd

2w + 7 = 2(5.5) + 7 = 11 + 7 = 18 yd

Answer 2

Answer

(Please I need a Brainliest)

I worked hard for this, bit I've done

Length= 18yd

Width=5.5yd

Explanation

lenght= 2x+7

width= x

The Area is=

$x \times (2x + 7)$

So, if x (width) is 5.5yd, the lenght will be 7yd more the the twice of X (2x+7=18yd)

Verify

The formula of the area will be

$5.5 \times 18 = 99{yd}^{2}$

I hope you're satisfied
