Charlie's garage has a rectangular floor space. Its length is 3 times its width. Charlie extends the width of his garage to 6 m,

Answer:

The percentage change is 140%

Step-by-step explanation:

Given

$L= 3W_1$ ---- initial dimension

$W_2 = 6m$ --- new width

$A_2 = 45m^2$ --- new dimension

Required

The percentage increment

The length remains constant because only the width is extended.

The new area is:

$Area =Length * Width$

$A_2=L * W_2$

Make L the subject

$L = \frac{A_2}{ W_2}$

Substitute values for A and W

$L = \frac{45m^2}{6m}$

$L = \frac{45m}{6}$

$L = 7.5m$ --- this is the length of the garden

Calculate the initial width:

$L= 3W_1$

Make W1 the subject

$W_1 = \frac{1}{3} * L$

$W_1 = \frac{1}{3} * 7.5$

$W_1 = 2.5$

So, the initial area is:

$A_1 = L_1 * W_1$

$A_1 = 2.5 * 7.5$

$A_1 = 18.75$

The percentage change in area is:

$\%A = \frac{A_2 - A_1}{A_1}$

$\%A = \frac{45 - 18.75}{18.75}$

$\%A = \frac{26.25}{18.75}$

$\%A = 1.4$

Express as percentage

$\%A = 1.4*100\%$

$\%A = 140\%$

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2+1 inches. She p

defon

Step-by-step explanation:

$perimeter \: of \: first \: pillow \: is \: \\ 4(2 {x}^{2} + 1) \\ perimeter \: of \: second \: pillow \: is \: \\ 4(4x - 7) \\ so \: we \: need \: compeletly \: 4(2 {x}^{2} + 1) + 4(4x - 7) \: ribbons. \\ 8 {x}^{2} + 4 + 16x - 28 = 8 {x}^{2} + 16x - 24 = \\ 8( {x}^{2} + 2x - 3) = 8(x + 3)(x - 1) \\ 8(3.5 + 3)(3.5 - 1) = 8(6.5)(2.5) = 8 \times 2.5 \times 6.5 = 20 \times 65 \times {10}^{ - 1} = 1300 \times {10}^{ - 1} = 130 \\ and \: we \: are \: done.$

i hope i have been useful buddy.

good luck ♥️♥️♥️♥️♥️.
