James states that quadrilateral

mr_godi [17]

Using the distance formula,

$AD=\sqrt{(-1-3)^{2}+(-3-(-4))^{2}}=\sqrt{17}\\\\BC=\sqrt{(5-9)^{2}+(1-0)^{2}}=\sqrt{17} \\\\\therefore \overline{AD} \cong \overline{BC}$

$AB=\sqrt{(-1-5)^{2}+(-3-1)^{2}}=\sqrt{52}=2\sqrt{13}\\\\CD=\sqrt{(9-3)^{2}+(0-(-4))^{2}}=\sqrt{52}=2\sqrt{13}\\\\\therefore \overline{AB} \cong \overline{CD}$

Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.

Mrs. Alberts built a pen for her dogs. The pen was 12.5 feet by 7 feet and had a concrete floor. If the concrete floor costs $12

dybincka [34]

Answer: Mrs. Alberts spent $1,050 on the floor.

Step-by-step explanation: First lets find the area to get the total amount of square feet by multiply length by width.

12.5 x 7 = 87.5 square ft.

We know that it costs $12 per square foot, and we have 87.5 square feet.

So, multiply 12 by 87.5 to find the cost that Mrs, Alberts will spend on the floor.

12 x 87.5 = 1050, or $1,050 for the total area of the floor.
