She turns left at `90^(@)` and walks to W which: is 4 ft away, turns `90^(@)` right and goes 3 ft to P, turns `90^(@)` i right and walks 1 ft to Q, turns left at `90^(@)` and goes to V, which is 1 ft away and once again turns `90^(@)` right and goes to R, 3 ft away. What is the distance between T and R.

Options

B. 5 ft
C. 7 ft
D. 8 ft

Answer

D

Explanation

From the Fig., it is clear that T to U, U to W, W to P, P to Q, Q to V and V to R are the movements of Beena.

Starting Point = T
End Point = R
`therefore` Therefore, distance between T and R
=TR=TU+ UR
=TU+PW+ QV
= (4 + 3 + 1) ft = 8 ft.
