<u>the question in English is</u>
THE SQUARE PERIMETER X IS TWO THIRDS OF THE SQUARE PERIMETER Y. THE PERIMETER OF THE SQUARE Y IS TWO THIRDS OF THE PERIMETER OF THE SQUARE Z. THE AREA OF THE SQUARE X IS 16 CM2 WHAT IS THE AREA OF THE SQUARE Z?
Let
Px--------> the perimeter of square x
Py--------> the perimeter of square y
Pz--------> the perimeter of square z
Ax--------> the area of square x
Az--------> the area of square z
Step 1
<u>Find the length side of the square x</u>
we know that
-------> equation A
-------> equation B
so
Step 2
<u>Find the perimeter of square x</u>
substitute the value of x in the formula
Step 3
<u>Find the perimeter of square y</u>
use the equation A
solve for Py
substitute the value of Px
Step 4
Find the perimeter of square z
use the equation B
solve for Pz
substitute the value of Py
Step 5
<u>Find the area of square z </u>
we know that
the area of the square z is equal to
<u>Find the length side of square z</u>
so
substitute the value of z in the area's formula
therefore
<u>the answer is</u>
the area of the square z is
