Question

of length 15 m and breadth 7 m, what is the area the cow can graze? What
is the area left ungrazed?​

Answer 1

Answer:

what is the length of rope with length of the rope its incomplete

Answer 2

Answer:

• 105m² is the area the cow can graze.
• 66.5m² is the area left ungrazed

Given :

• Length is 15m
• Breadth is 7m

To find :

• What is the area of the cow can graze
• Is the area left ungrazed?

Solution :

As we know that,

• Area = length × breadth

Where,

• length is 15m
• breadth is 7m

》Area = length × breadth

》15 × 7

》105 m²

Hence, 105m² is the area the cow can graze.

Now , we have to find the what is the area left ungrazed then,

• 1/4 × πr²

We know that 1/4 circle can be covered when the cow is tied so , it will be rectangle of the corner

》1/4 × πr²

Where , r is 7m

》1/4 × 22/7 × 7²

》1/4 × 22/7 × 7 × 7

》1/4 × 154

》38.5m²

Now,

• 105 - 38.5 = 66.5m²

Hence, 66.5m² is the area left ungrazed

• 105m² is the area the cow can graze.
• 66.5m² is the area left ungrazed
