Question

(ii) In Fig. 2.4, a boy travels 4 km towards east and
then 3 km towards north. The total distance travelled
by the boy is OA + AB = 4 km + 3 km = 7 km,
but the displacement of the boy is OB = 5 km in

Answer 1

Answer:

The answer is 5 because of the

Phythagoras Theorem

Step-by-step explanation:

It"s formula is

(AC)2 =(AB)2 + (BC)2

So we can take

AB= 4cm

BC= 3cm

So putting the value of AB and BC

we get

(AC)2= 4×4 + 3×3

(AC)2= 16 +9

(AC)2= 25

AC = 5 (5)2 = 25

Hence the displacement is 5cm
