Question

Please help me with this maths question

Answer 1

12

Explanation:

The formula for the area of a square is
`A=`
`b^2`.

Therefore, in this case we have
`144=b^2`.

Taking the square root on both sides, we get ±12, but there can't be a negative side length so thus b is 12.

Hope this helps!

Answer 2

B = 12

Explanation:

A= 144

B= 12

12 × 12 = 144

B×B = A

hopefully this helps you
