find the length of a side of a square with an area of 169 m^2. model with a quadratic equation, then solve.

Question

i need to find the sode length of the square

Answer 1

A square has sides of equal length all around. 

 

A = L²

 

where:

A = area

L = side

 

L² = 169

 

Knowing this, can you complete the rest?

Answer 2

Hi Kayla,

Since we know that the area of a square (A) is equal to the length of any side (since they're the same length) squared (x²), we can say: A=x²=169

The square root of 169 is the length of a side of the square.
