Supriya is decorating her bedroom. She plans to hang strings of twinkle lights all the way around her walls. She measures the walls and finds she will need 363636 meters of lights.
Which measurement did Supriya find?

Supriya found the Perimeter of the bedroom.

Step-by-step explanation:

Supriya plans to hang the string of twinkle lights all the way around her walls. This is equivalent to making a boundary around the walls using the twinkle lights.

In geometry the boundary of a figure refers to its Perimeter. So, this means the measurement which Supriya found was the Perimeter of her room. Perimeter is defined as the sum of all the sides of a figure. Room is a 4-sided figure i.e. a quadrilateral, and most likely it will be in shape of a rectangle. Perimeter of a rectangle is calculated as:

Perimeter = 2 ( Length + Width )

So, the perimeter of Supriya's bedroom is 36 meters.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
