Find the perimeter of a square whose area is 168cm square​

51.84 cm

Step-by-step explanation:

Solution,

Area of square = 168 cm²

L²= 168 cm²

L= √168cm²

L= 12.96 cm

Now,

Perimeter of square= 4L

=4×12.96 cm

=51.84 cm

Here,

Area of square = 168 cm^2

Perimeter of square = ?

Now,

Area of square = 168 cm^2

or, l^2 = 168

◆ l = 12.96 cm

Then,

◆Perimeter of square = 4l

= 4*12.96

= 51.84 cm

It is a right answer...

I hope you understand...

Answer is B. x^7 - 4x^5 + 2x^4 + 4x^3 - 10
Here are a few rules of order
1. X values are always first, then y values
2. The highest exponent within that variable goes first (x^7 comes before x^5)
3. Numbers come after variables
Don't let the coefficients trick you since they are irrelevant if the exponent is higher. Automatically we know that -10 goes last because it is just a number. Then, you just order the x's from highest to lowest.
