Answer:
2 blocks shorter
Step-by-step explanation:
Using Pythagoras :
Distance from Charles house straight to gamestop = d
d = sqrt(4² + 3²)
d = sqrt(16 + 9)
d = sqrt(25)
d = 5 blocks
If he takes the Indirect route :
Total distance = (4 blocks + 3 blocks) = 7 blocks
Hence, taking the straight route to Gamestop, his trip will be (7 blocks - 5 blocks) = 2 blocks shorter
