Answer:

392 ft

Step-by-step explanation:

Hello, Let me help you with this

to find the real length and width you can use a rule of three

Step 1

length=8 in

Let

if

2.5 in ⇔ 35 ft

8 in ⇔ X ft ?

the relation is

\frac{2.5\ in}{35\ feet}=\frac{8\ in }{x}\\\\solve\ for\ x\\\frac{x*2.5\ in}{35\ feet}=8\ in\\x*2.5\ in=8\ in *35\ feet\\x=\frac{8\ in *35\ feet}{2.5\ in}\\ x=112\ ft  

Step 2

width=6 in

Let

if

2.5 in ⇔ 35 ft

6 in ⇔ X ft ?

the relation is

\frac{2.5\ in}{35\ feet}=\frac{6\ in }{x}\\\\solve\ for\ x\\\frac{x*2.5\ in}{35\ feet}=6\ in\\x*2.5\ in=6\ in *35\ feet\\x=\frac{6\ in *35\ feet}{2.5\ in}\\ x=84\ ft  

Step 2

find the perimeter using

Perimeter = 2*length +2* width

replacing

Perimeter= 2*112 ft +2* 84 ft

Perimeter=224 ft +168 ft

Perimeter=392 ft

Have a nice day

Well if I did my math correctly I do believe the perimeter should be 392 ft.


6÷2.5= 2.4
2.4×35=84

8÷2.5= 3.2
3.2×35=112

84×2
112×2

392

Three sets of a sum of a number and four are added to the sum of 7 times the same number and 13
Reika [66]
Let
x--------------> a number

we know that
<span>three sets of a sum of a number and four----------> 3(x+4)
t</span><span>he sum of 7 times the same number and 13--------> 7x+13

therefore

</span>(Three sets of a sum of a number and four) are added (to the sum of 7 times the same number and 13) ----------> [3(x+4)] + [7x+3]

[3(x+4)] + [7x+3]------> [3x+12] + [7x+3]=10x+15

the answer is 10x+15
