Answer:

area: 114 square units
perimeter: 44 units

Step-by-step explanation:

The figure is a trapezoid with bases 12 and 7, and a height of 12. The area formula is ...

A = (1/2)(b1 +b2)h

A = (1/2)(12 +7)(12) = 114 . . . square units area

The length of side AB can be found using the distance formula:

d = √((x2 -x1)^2 +(y2 -y1)^2)

d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13

The sum of the side lengths is then ...

13 +7 +12 +12 = 44 . . . units perimeter

Answer:

You could make a proportion, and divide or subtract the colors you like the least. Then, take the ones that you like the least away and put them in a separate place away from the others. For example: You have five colors, right? Ok, lets say your colors are blue, charcoal gray, yellow, green, and lilac.

Lets say your favorites are charcoal gray, lilac, and blue. (3/5)

So you put yellow and green to the side (2/5)

For example: You have 6 wallpaper patterns, right? Lets say your patters are flowers, dots, lines, stars, circles, and zigzags.

Lets say your favorites are flowers and stars. (2/6 or 1/3)

So you put dots, lines, circles, and zigzags to the side. (4/6 or 2/3)

Now, I want you to narrow your favorites down to what you favor more out of them. Now you have 3 paint colors, right? Your colors are charcoal gray, blue, and lilac. You need to narrow it down to 1 favorite. Lets say you choose the the lilac best.

Now you have 2 patterns, right? Your patterns are flowers and stars. You need to narrow it down to your favorite pattern. Lets say you choose the stars.

So, you will paint your wall lilac with the pattern of stars.

In □PQRS side PQ∥ side RS. If m∠P = 108degree

natka813 [3]

<h2>Given :-</h2>

In □PQRS side PQ∥ side RS. If m∠P = 108degree

and m∠R = 53degree

m∠Q and m∠S.

<h2>Solution :-</h2>

According to angle sum property

P∠Q=180−∠P

∠Q=180−108

$\boxed{\sf{\angle Q = 72°}}$

For angle S

∠S=180−∠R

∠S=180−53

$\boxed{\sf {\angle S = 127°}}$

A circle has a radius of 5 centimeters. What is the area?

schepotkina [342]

Answer:

$25\pi$

Step-by-step explanation:

The formula for the area of a circle is $A=\pi r^{2}$ , r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however $25\pi$ is the exact answer.
