Find the perimeter of rectangle BCEF. Round your answer to the nearest hundredth

777dan777 [17]

Answer:

The perimeter of the rectangle B C E F is 16.97 units

Step-by-step explanation:

* Lets explain how to solve the problem

- B C E F is a rectangle

- The perimeter of the rectangle is the sum of the length of its

four sides

- The coordinates of the vertices of the rectangle are:

B (0 , 3) , C (4 , -1) , E (2 , -3) , F (-2 , 1)

- To find the dimensions of the rectangle use the rule of distance

d = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

* Lets solve the problem

∵ $(BC)=\sqrt{(4-0)^{2}+(-1-3)^{2}}=\sqrt{16+16}=\sqrt{32}$

∵ $(CE)=\sqrt{(2-4)^{2}+(-3--1)^{2}}=\sqrt{4+4}=\sqrt{8}$

∵ $(FE)=\sqrt{(2--2)^{2}+(-3-1)^{2}}=\sqrt{16+16}=\sqrt{32}$

∵ $(BF)=\sqrt{(-2-0)^{2}+(1-3)^{2}}=\sqrt{4+4}=\sqrt{8}$

∵ The perimeter of the rectangle = BC + CE + FE + BF

∴ The perimeter = $\sqrt{32}+\sqrt{8}+\sqrt{32}+\sqrt{8}=16.97$

∴ The perimeter of the rectangle B C E F is 16.97 units

Val buys a computer for $920. If this is 115% of what the store paid for the same computer, how much did the store earn on the s

noname [10]

Hi!

We will solve this using rations, like this:

$920 equals to 115% = 1,15

$x equals to 100% = 1

_______________________

x = (920*1)/1,15

x = 920/1,15

x = 800

Store earned 15%, or in this case 920 - 800 = $120.

Hope this helps!
