Answer 1

Step-by-step explanation:

$\sf{\bold{\blue{\underline{\underline{Given}}}}}$

●The cost of 1 square field=35$

●Total cost =4480$⠀⠀⠀⠀

$\sf{\bold{\red{\underline{\underline{To\:Find}}}}}$

☆length of each side of the field???⠀⠀⠀⠀

$\sf{\bold{\purple{\underline{\underline{Solution}}}}}$

Let the side of the square=$a$⠀⠀⠀

It's perimeter =$4×side=4a$

According to the question,

perimeter ×35$=4480$

:$\implies{4a×35=4480}$

:$\implies{140a=4480}$

:$\implies{a=\frac{4480}{140}}$

:$\implies{a=\frac{\cancel{4480}}{\cancel{140}}}$

:$\bold{a=32}$

$\sf{\bold{\green{\underline{\underline{Answer}}}}}$

$\therefore$Length of the each side is $\pink{32cm.}$ ⠀⠀⠀

Answer 2

QUESTION:

The cost of putting a fence around a square field at ₹35 per metre is ₹4480. Find the length of each side of the field.

SOLUTION:

Given:

• Cost of fence around a square field = ₹35
• Total cost = ₹4480

We have to find the length of each side of the field.

Remember :

Perimeter of a square = 4 × side

To find each side of the field

= 4 × side × 35

as the total cost = ₹4480

So ,

4 × side × 35 = 4480

= 140 × side = 4480

= Side = $\frac{4480}{140}$

Side = 32 m

So , the length of each side of the square field is 32m
