If the area of a square plot of land is 9 miles squared, what is the perimeter of this land?

tatyana61 [14]

Answer:

$\huge{ \fbox{ \sf{12 \: miles}}}$

Step-by-step explanation:

Given,

Area of a square plot = 9 miles

First, finding the length of the land

$\boxed{ \sf{Area \: of \: a \: square \: = \: {length}^{2} }}$

$\mapsto{ \sf{9 = {length}^{2} }}$

$\mapsto{ \sf{ {length}^{2} = 9}}$

$\mapsto{ \sf{ \sqrt{ {(length)}^{2} }} = \sqrt{9} }$

$\mapsto{ \sf{length = 3 \: miles}}$

Now , finding the perimeter of the land :

$\boxed{ \sf{perimeter \: of \: a \: square = 4 \: * length}}$

$\mapsto{ \sf{perimeter \: = \: 4 \: * \: 3}}$

$\mapsto{ \sf{perimeter \: = 12 \: miles}}$

The perimeter of the land = 12 miles

Rodrigo practiced playing the guitar for 15 1/3 hours over the past 3 weeks. He practiced for 6 1/4 hours during the first week

Yuri [45]

Add up the sum and divide.

Practice Chart
1st Week: 6.25 Hours
2nd Week: 4.66 Hours
3rd Week: 15.33 - (1st Week + 2nd Week)

Solve:
6 1/4 + 4 2/3 = 10 8/12 or 10 2/3

15 1/3 - 10 2/3
14 4/3 - 10 2/3
4 2/3 hours practiced third week

Hope this helps!
