Answer:

ABCD is a RHOMBUS or a SQUARE.

Step-by-step explanation:

The coordinates are A(-6, 6), B(-2, 8), C(0, 4), and D(-4, 2).

By DISTANCE FORMULA:

The length of the segment with coordinates X(a,b) and Y(c,d) is given as:

$XY = \sqrt{(c-a)^2 + (d-b)^2}$

Now, similarly, the lengths of the segments are:

$AB = \sqrt{(-2 -(-6))^2 + (8-6)^2}$

$=\sqrt{(4)^2 + (2)^2} = \sqrt{16 + 4} = \sqrt{20}$

⇒ The length of the segment AB = √ 20 units

$BC = \sqrt{(0 -(-2))^2 + (4-8)^2}$

$=\sqrt{(2)^2 + (-4)^2} = \sqrt{4 + 16} = \sqrt{20}$

⇒ The length of the segment BC = √ 20 units

$CD = \sqrt{(0 -(-4))^2 + (2-4)^2}$

$=\sqrt{(4)^2 + (-2)^2} = \sqrt{16 + 4} = \sqrt{20}$

⇒ The length of the segment CD= √ 20 units

$AD = \sqrt{(-6 -(-4))^2 + (6-2)^2}$

$=\sqrt{(-2)^2 + (4)^2} = \sqrt{4 + 16} = \sqrt{20}$

⇒ The length of the segment AD = √ 20 units

$AC = \sqrt{(0 -(-6))^2 + (4-6)^2}$

$=\sqrt{(6)^2 + (-2)^2} = \sqrt{36 + 4} = \sqrt{40}$

⇒ The length of the diagonal AC = √ 40 units

$BD = \sqrt{(-2 +4)^2 + (8-2)^2}$

$=\sqrt{(2)^2 + (6)^2} = \sqrt{36 + 4} = \sqrt{40}$

⇒ The length of the diagonal BD = √ 40 units

Since, here the length of all segments is √ 20 units.

⇒AB = BC = CD = AD = √ 20 units

and Diagonal AC = BD

⇒ ABCD is a RHOMBUS or SQUARE.

Mr Floyd is laying grass squares in his backyard. He will cover the entire yard except for the vegetable garden. How many square

Alenkasestr [34]

Here we can first find the area of yard and then subtract the area of vegetable garden to get the required area.

The formula to find area is given by:

$A = l* w$

Now we find area of yard:

length is 25 ft and width is 15 ft.

$A = 25 * 15$

Area of yard = 375 ft²

Area of vegetable garden:

length = 8ft and width =8ft

So the vegetable garden is a square.

Area = 8*8

Area of vegetable garden =64 ft²

Area of backyard to be laid with grass = Area of yard-Area of vegetable garden

Area required = 375 -64 = 311 ft²

Answer : The area of backyard in which grass is to be laid is 311 square feet.

3. What is the radius of a circle whose area is 64π cm squared?

nataly862011 [7]

Answer:

Area = 64π

Area \: = \pi {r}^{2}Area=πr

64 \: \pi \: = \pi {r}^{2}64π=πr

{r}^{2} = \dfrac{64\pi}{\pi}r

64π

{r}^{2} = 64r

=64

r \: = \: \sqrt{64} = 8r=

Radius = 8 units

Finding the Diameter -

Diameter = Radius x 2 = 8 x 2 = 16 .

\bold{Diameter \: is \: 16 \: units}Diameteris16units
