Question

The area of a rectangle is 105 square units. Its width measures 7 units. Find the length of its diagonal. Round to the nearest tenth of a unit.

Answer 1

Answer:

16.6

Step-by-step explanation:

The rectangle has an area of 105. It's width is 7.

1: Find the length

     $\frac{area}{width}$=length

     $\frac{105}{7}$= 15

      Length=15

2: Pythagorean theorem

      $a^{2} +b^2=c^2$

       $7^{2}$+$15^2=c^2$

       49+225=$c^2$

        275=$c^2$

         $\sqrt{275}$ = $\sqrt{c^2\\}$

          16.55≈c

           Rounded to nearest tenth

              16.6
