The coordinate grid shown represents a map of a park. A portion of the park is going to be upgraded with new playground equipment and flowers.Part AThe portion of the park that is to receive upgrades has the following coordinates:Point A (-4, 4)Point B (3, 4)Point C (3, -2)Point D (-4, -2)Use the Add Point and Connect Line Tools to create the rectangle ABCD.Part BEach unit of the grid represents 1 yard. How much area, in square yards, will receive upgrades?Part CThe triangular area between points A, B, and D will be decorated with red, white and blue flowers. 1/3 of triangle ABD will have red flowers. How much area, in square yards, will have red flowers?



Answer :

Answer:

[tex]Area=7yards^2[/tex]

Explanation:

We were given the following information:

PART C

The triangular area between points A, B, and D will be decorated with red, white and blue flowers

1/3 of triangle ABD will have red flowers

The area of a triangle is given by:

[tex]\begin{gathered} Area_{triangle}=\frac{1}{2}\times Base\times Height \\ Base=4-(-2)=4+2=6units \\ Height=3-(-4)=3+4=7units \\ Area_{triangle}=\frac{1}{2}\times6\times7 \\ Area_{triangle}=21units^2 \\ 1unit^2=1yards^2 \\ \Rightarrow Area_{triangle}=21yards^2 \\ \\ \therefore Area_{triangle}=21yards^2 \end{gathered}[/tex]

The area having red flowers is calculated as shown below:

[tex]\begin{gathered} Area_{red}=\frac{1}{3}\times Area_{triangle} \\ Area_{red}=\frac{1}{3}\times21 \\ Area_{red}=7yards^2 \\ \\ \therefore Area_{red}=7yards^2 \end{gathered}[/tex]

Therefore, the area of the triangle that will have red flowers is 7 square yards
