1 . ( b ) 225 sqm is the correct answer

Answer 2

Answer:

1.B)

2.D)

Step-by-step explanation:

1.Given,

The area of a square is 60 cm

We know,,

Perimeter of a square

4(One side of a square) = Perimeter of the square

Or, 4(x) = 60 cm

Or, 4x = 60 cm

Or x = 60/4 cm

Or, x = 15 cm

Therefore, the one side of a square is 15 cm

We know,

Area of a square:

(One side × One side) Sq. Unit

=(15×15) cm2

=225 cm2

So the area of the square whose perimeter is 60 cm is 225 cm

(Ans)

2.Given,

Jatin and Priya have together 41. Jatin has 2 more then Priya

Let,

Priya has x

Jatin has (x+2) [As Jatin has 2 more than Priya]

According to the question,

x+(x+2) = 41

Or, x+x+2 = 41

Or, 2x+2 = 41

Or, 2x = 41-2

Or, 2x =39

Or, x = 39/2

Or, x = 19 1/2 or 19.5

So, Jatin has 19.5

(Ans)
