Aplot of land contains a 16-ft-by-20-ft garden, which is surrounded by a 2-ft wide wall on all sides. what is the perimeter of the entire plot of land?

88 ft

Step-by-step explanation:

Given,

The measurement of the garden = 16-ft-by-20-ft,

That is, length of garden = 16 ft,

Width of garden = 20 ft,

If plot is obtained after surrounding the garden by 2 ft wide wall,

So, length of plot = 16 + 4 = 20 ft,

Width of plot = 20 + 4 = 24 ft,

So, the perimeter of the entire plot = 2 ( length + width )

= 2 ( 20 + 24 )

= 88 ft

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
