Answer:

The original side length was 5 in.

Step-by-step explanation:

Area of new square is (side length)^2.  Here,

that area is (x + 2)^2 = 49 in^2, and we must find x.

Taking the square root of both sides, we get:

x + 2 = +√49 = +7

Subtracting 2 from both sides yields x = -2 + 7 or x = 5

Check:  does (5 + 2)^2 = 49?  YES

Carly lives in Scottsdale, AZ and plans to go visit downtown Glendale, AZ. The map with a scale of 2 cm for every 4 km shows the
AleksandrR [38]
Comparing map distance to real distance we get 2cm/4km. That means 1cm = 2km.

So the map distance is half the real distance (well, technically not as one is in cm and the other in km but it’s enough to think this way) and a real distance of 10km must mean a map distance of half that (again ignoring the units) so we get 5cm.
