Question

the side of a triangular field are 25m and 20m and 16m find the total distance covered by a girl intaking 2 round of a field

Answer 1

Answer:

Now firstly sides of a triangular field are=

25m, 20m and 16m

totao distance =25+20+16=61

distance covered by a girl in 1 round =61m

distance covered byva girl in 2 rounds =61×2 =122m

Answer 2

☯ Given sides of a triangular field are 25 m , 20 m and 16 m.

☯ We have to find, Total distance

covered by a girl intaking 2 round of a field.

${\bf{Here}} \begin{cases} & \text{AB = 25 cm } \\ & \text{BC = 20 cm } \\ & \text{AC = 16 m} \end{cases}$

$\star\;{\boxed{\sf{\purple{Perimeter_{\triangle} = Sum\;of\;all\;sides}}}}$

$\dag\;{\underline{\frak{Putting\;values,}}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 25 + 20 + 16$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\purple{61\;m}}}}}\;\bigstar$

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Distace travelled in 1 round by girl = Perimeter of field

Distace travelled in 2 round by girl = 2 × Perimeter

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 2 \times 61$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\purple{122\;m}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ Total distance covered by a girl in taking 2 round of field is 122 m.

• Area of triangle = $\sf \frac{1}{2} \times b \times h$

• Area of square = side × side

• Area of Rectangle = l × b

• Perimeter of Square = 2(l + b)

• Perimeter of Square = 4 × side
