Question

the length and breadth of the field are measured is (200 + - 5 )m and (100+-4)m respectively.what is the area of the field?

Answer 1

Answer:

18720m per square unit

Explanation:

length=200+-5m

breadth=100+-4m

So area=l•b

=(200-5)(100-4)

=200(100-4)-5(100-4)

=20000-800-500+20

=20020-1300

=18720m per square unit

Answer 2

Therefore the area of the field is 18,720 m².

Given:

The length of the field = ( 200 + ( -5 ) ) = 195 m

The breadth of the field = ( 100 + ( -4 ) ) = 96 m

To Find:

The Area of the field.

Solution:

The given question can be solved very easily as shown below.

Given that,

The length of the field = l = ( 200 + ( -5 ) ) = 195 m

The breadth of the field = b = ( 100 + ( -4 ) ) = 96 m

The Area of the rectangle = Length × Breadth

⇒ The Area of the field = l × b

⇒ The Area of the field = 195 × 96 = 18,720

Therefore the area of the field is 18,720 m².
