Question

Neighborhood block: Perimeter Perimeter = 3 20 + w + 3 20 + w Bijan wants to go running during his family’s vacation to New York City. To do so, he will run a neighborhood block 20 times. Bijan runs a total of 8 miles. Use the formula for the perimeter of the neighborhood block and the reciprocal to find the width w of the city block.

Answer 1

20(3/10 + 2w)
6 + 40w = 8
40w = 8 - 6
= w = 2 / 40
simplified 2/40 1ould be 1/20

The answer is 1/20

Answer 2

The perimeter of a rectangle is the sum of all sides of the rectangle. Then the width of the city block is 100 units.

What is a rectangle?

It is a polygon that has four sides which are obtained from a parallelogram whose all the angles are 90 degrees.

Perimeter of rectangle

Perimeter of rectangle = 2 (Length + Width)

Given

Length = 3/20Width = w

He will run a neighborhood block 20 times.

Bijan runs a total of 8 miles.

To find

The width of a city block.

So for one time he runs will be

$= \dfrac{8}{20} = 0.32$

Perimeter = 0.32 mile

Then width will be

$\begin{aligned} \rm Perimeter\ of\ rectangle\ &= \rm \ 2\ (\ Length\ +\ Width)\\\rm 0.32 &= \rm 2*(\dfrac{3}{20} +w)\\\rm 0.16 &= \rm \dfrac{3}{20} + w\\ \rm \dfrac{4}{25} - \dfrac{3}{20} &= \rm w\\\rm w &= 0.01\end{aligned}$

Then the width of a city block will be

$\rm The\ width\ of\ city\ block\ = \dfrac{1}{w} =\ 100$

Thus, the width of the city block is 100 units.
