Answer:

Step-by-step explanation:

1 yard = $7.99

0.51 yard = x

cross multiply

1 (x) = ($7.99 × 0.51)

1 (x)/1 = 4.0749/1

x = 4.07

Around 4.07 because 799x51 is 40749. 40749 divided by 10000 is 4.0749 rounded to the nearest two decimal is 4.07.

Answer:

$\large{ \tt{❃ \: EXPLANATION }}:$

Firstly , See the attached picture! :) I splitted the provided figure into two rectangles i.e namely small rectangle & big rectangle !

$\large{ \tt{❁ \: LET'S \: START}} :$

Find out the area of small rectangle having length of 14 ft & width of 12 ft :

$\large{ \tt{ ↦ AREA\: OF \: SMALL \: RECTANGLE= L \times W = 14 \times 12 = \boxed{ \tt{168 \: {ft}^{2} }}}}$

Find out the area of big rectangle having length of 20 ft and width of 19 ft :

$\large{ \tt{↦AREA \: OF \: BIG \: RECTANGLE = L \times W = 20 \times 19 = \boxed{ \tt{380 \: {ft}^{2} }}}}$

Now , Add the area of small rectangle & area of big rectangle :

$\large{ \tt{☄ \:TOTAL \: AREA = AREA \: OF \: SMALL \: RECTANGLE + AREA \: OF \: BIG \: RECTANGLE}}$

$\large{ \tt{⇢168 \: {ft}^{2} + 380 \: {ft}^{2} }}$

$⇢ \boxed {\boxed{ \large{ \tt{548 \: {ft}^{2} }}}}$

$\large{ \boxed{ \tt{⇝ \: OUR\: FINAL\: ANSWER : \boxed{\underline{ \tt{D. \: 548 \: {ft}^{2} }}}}}}$
