Astudent was asked to use the formula for the perimeter of a rectangle, p = 2ℓ 2w, to solve for ℓ. the student came up with an answer, p − 2w = 2ℓ. what error did the student make? complete the explanation. then solve for ℓ.

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.
