What is the area of a section of pavement that is 10 ft wide and 70 yd​ long? Give your answer in square feet.

Answer:The area of the section of pavement is 2100 square feet.Step-by-step explanation:This section of pavement has a rectangular format.The area of the rectange is:[tex]A = l*w[/tex]In which l is the length and w is the width.The problems asks the area in square feet. This means that both the width and the length must be measured in feet.The width is 10 ft, so there is no need for conversion;The length is 70yd. We must convert 70yd to feets.Each yard has 3 feet. How many feet are there in 70 yards?1 yd - 3ft70 yds - xft[tex]x = 3 * 70[/tex][tex]x = 210[/tex] feet,So, this section of pavement is 10 ft wide and 210 ft wide. So [tex]l = 10[/tex] and [tex]w = 210[/tex]. There area in square feet is:[tex]A = l*w[/tex][tex]A = 10*210[/tex][tex]A = 2100[/tex] square feet;The area of the section of pavement is 2100 square feet.
