Step-by-step explanation:
The formula for the area of a square is:
A
=
s
2
Where:
A
is the area of the square.
s
is the length of the side of a square.
Substituting and solving for
s
gives:
225
cm
2
=
s
2
We can take the square root of each side of the equation giving:
√
225
cm
2
=
√
s
2
15
cm
=
s
s
=
15
cm
The formula for the perimeter of a square is:
p
=
4
s
Where:
p
is the perimeter of the square.
s
is the length of the side of a square.
Substituting for
s
from the solution for the previous formula and calculating
p
gives:
p
=
4
×
15
cm
p=60cm

Solution :
It says multiply 8 by 12 and then add 9
reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .
Let us first write multiplying 8 and 12 which makes it 8 x 12
the result is being add to 12 so we place 8x12 in parenthesis then add 12
which , makes it : ( 8x12) + 9
this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .
we can write it without parenthesis like : 8x12 +9
Answer is third option .

Answer:
Below
Step-by-step explanation:
Area if cuboid =2(l*b+b*h+h*l)
= 2(7.5*5+5*2.3+2.3*7.5)
=2(37.5+11.5+17.25)
=2(66.25)
=103.75cm^3
The answer is B, 50 miles!
