Of the two square fields, the area of one is 1 hectare while the other one is broader by 1%. The difference in their areas is
Answer is 201 m sq please explain it and give right answer​

Answer 1

The difference in the areas of the two square fields is 201-meter square.

Step-by-step explanation:

Step 1:

Area of the first square filed is given as = 1 hectare = 10⁴ m²

Let the side of the first square field be denoted as “s₁” m.

Since the area of square = side²

∴ s₁ = √[10⁴] = 100 m

Step 2:

Let the side of the second square field be denoted as “s₂” m.

It is given that the second field is 1% broader than the first field, therefore,

s₂ =  s₁ + (1% of s₁) = 100 + (0.1*100) = 101 m

Step 3:

Thus,  

The difference in the areas of the two square fields is given as,

= [s₂]² – [s₁]²

= [101]² – [100]²

= 10201 – 10000

= 201 m²
