A square part of side 20 meters has a footpath along the boundary of width 10 meters. Find the area of parth.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
