The smaller square in the figure below has a perimeter of $4$ cm, and the larger square has an area of $16$ $\text{cm}^2$. What is the distance from point $A$ to point $B$? Express your answer as a decimal to the nearest tenth.
Draw a line straight across from point B...then you have a right triangle with legs 5 and 3
the hypotenuse is BA sqrt (3^2 + 5^2) = ~5.8 units
