Two squares are similar. The
Pepsi [2]

Answer:

The perimeter of the second square is 36 inches

Step-by-step explanation:

Given

Represent the sides of the squares with S1 and S2.

So:

S_1:S_2 = 1 : 3 --- Scale factor

P_1 =12 --- perimeter of the first

Required

Calculate P2, the perimeter of the second

Represent the ratios of the perimeter:

Scale = P_1 : P_2

Substitute 12 for P1

Scale = 12 : P_2

Equate both scale factors

12 : P_2 = 1:3

Convert to fraction

\frac{12}{P_2} = \frac{1}{3}

Cross multiply

P_2 = 12 * 3

P_2 = 36

I am Lyosha [343]
In math, the word unknown is also called to the missing term of a number sentence. This missing term is a missing piece that has to be solved.
Let us have A x 60 = 120, since A has no numerical value, it is considered as the missing term. How can we get the value of the missing term? first, study the number sentence. Find out the rule, then apply it.
The value of A on the equation above is 2. Here's how:
A x 60 = 120
A=120÷60
A=2
The value A is 2, therefore the missing term is 2.
