☯Dear User!☯

Question: four cows are tethered at four corner of a square field of 70m side as shown in given figure so that they can reach each other. what area of the field will remain unglazed ?

Answer:  Required Area Of  Field Of Remaining Ungrazed Filed = 1050 m²

Method of Solution:

In this Question, It is given four cows are tethered at four corner of a square field of 70m side,

Side of Square = 70 Meters

Now, According to the Question's Statement!

Statement:  four corner of a square field of 70m side as shown in given figure so that they can reach each other.  

Now, From Given Figure,

Area of Square = (70×70)m²

Area of Square=49,00m²

Now,  Area of Four Corners as shown in figure!

Area of Four Corners = [4×π(35)²×90÷360]m²

Area of Four Corners = 1385,442m²/360

Area of Four Corners = 3850m²

Now, According to the Question's Statement!

area of the field  remain ungrazed = Area Of  Square - Area Of Four Corners

Area Of  Field Of Remain Ungrazed = 4900 - 3850 m²

•°• Area Of  Field Of Remain Ungrazed = 1050 m²

Hence, Required Area Of  Field Of Remaining Ungrazed Filed = 1050 m²

Answer 2

Answer: 1050m²


Step-By-Step Explanation:

four cows are tethered at four corner of a square field of 70m side,

Side of Square = 70

So, Area of Square = 70×70m²

Area Of Square = 4900m²

Now, According to the Question#

Area of ungrazed field= Area of square- Area of 4 quarters
                                 

Side × Side - 4×∅/360πr²

(70×70) - 4 ×90/360 × 22/7×(35×35)

= 4900 - 3850

= 1050m²

Therefore. Area of Ungrazed is 1050m²
