Question

the length of a 1.5 m high pole at a certain time of the day is 2.5 m. what the height of another pole whose shadow at that time is 3.5 m long?

Answer 1

★Given:-

• The length of a 1.5 m high pole at a certain time of the day is 2.5 m.

★To find:-

• Height of another pole.

★Solution:-

$\color{pink}\frac{1.5}{2.5} = \frac{x}{3.5} \\ \color{purple}2.5 \times x = 3.5 \times 1.5 \\ \color{magenta}x = \frac{3.5 \times 1.5}{2.5} = 2.1 \\ \color{lime} x = 2.1m$

Hence, Height Of Another pole is 2.1m

Answer 2

Answer:

✡ Answer ✡

➡$\frac{1.5}{2.5} = \frac{x}{3.5 }$

➡$2.5 \times x = 3.5 \times 1.5$

➡$x = \frac{3.5 \times 1.5}{2.5} = 2.1$

➡$x = 2.1m$

Hence, Height of another pole is 2.1m.
