Answer 1

Answer:

A person moves along the boundary of a square park of side 10m in 40s. What will be the magnitude of displacement of that person at the end of 2 minutes 20 seconds

Answer 2

Step-by-step explanation:

Let the side be x

3x and 4x .

The perimeter of the parallelogram is 2 ( 3x+4x) = 2 × 7 = 14x .

The given data implies that 42 = 14x , so that

x = 42 / 14 = 3

Hence , the sides of the parallelogram are 3×3 = 9 cm

and ,

3 × 4 = 12 cm
