The length of a rectangle is 14 meters. If the perimeter of the rectangle is 44 meters, what is the width?

weeeeeb [17]

In a rectangle the opposite sides are equal. So if the perimeter is 44 meaning all sides added up equal 44. Then you can subtract 14 twice because there are two 14 length sides. That will result in 16. Then divide by 2 because there are two side lengths that are the widths. This results in 8. The correct answer is A. 8m

A rectangular garden has a length of (2y - 4) feet and a width of 4y^2 feet. How do you find the perimeter of the garden

Ber [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 {y}^{2} + 4y - 8}}}}}$

Step-by-step explanation:

Given,

Length of a rectangular garden ( l ) = 2y - 4

Width of a rectangular garden ( w ) = 4y²

Perimeter of the garden = ?

Finding the perimeter of a rectangular garden having length of 2y-4 and width of 4y²

$\bold{ \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}}$

$\longrightarrow{ \sf2(2y - 4 + 4 {y}^{2}})$

Distribute 2 through the parentheses

$\longrightarrow{ \sf{4y - 8 + 8 {y}^{2} }}$

Arrange it in standard form

$\longrightarrow{ \sf{8 {y}^{2} + 4y - 8}}$

Hope I helped!

Best regards! :D

Alex needs 80 cm of thread for a sewing project. The thread is on a spool with a circumference of 10 cm. How many times must ale

Mrrafil [7]

Answer:

If the spool has 10 cm of circumference or perimeter, this means that 10 cm of thread fits the whole circumference of the spool, which also means that

<h2>1 unwind is equivalent to 10 cm of thread. </h2>

Then, we have to make the following question:

If 10 cm of thread is equivalent to 1 unwind, to how many unwinds is equivalent 80 cm of thread?

If we want to know how many time does Alex need to unwind the spool, we can use the following relation also called the Rule of Three:

$10 cm----1 unwind$
