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

A local shop sells frozen yogurt in four flavors. The yogurt comes in a small, medium, or large cup. A customer can top the yogu

Rasek [7]

Answer: 36 (maybe)

Step-by-step explanation:

For each sized cup, there is an option of 4 flavours. Which also have the option of 3 toppings

Example:

- Small - 1 - 3 toppings

2 - 3

3 - 3

4 - 3

So 1 x 4 x 3 = 12

Since there is 3 cup sizes, multiply that by 3 = 36

Not sure if that's right but hope it helps somehow
