1. perimeter= 30 area=60
2. perimeter= 34 area=72.25
3. perimeter = 60 area = 90
4. perimeter = 60 area = 225

Answer 1

Answer:

225

Step-by-step explanation:

6*2.5=15

6*2.5=15

15*15=225

Answer 2

The perimeter and area of square is $60cm$ and $225cm^{2}$ respectively.

Option 4 is correct.

Area and Perimeter :

It is given that, side of square is enlarged using a scale factor of 2.5.

So that, new side of square is,

                                 $=6*2.5=15cm$

Perimeter of square is,

                            $=4*15=60cm$

Area of square is,

                             $=15815=225cm^{2}$

Thus, the perimeter and area of square is $60cm$ and $225cm^{2}$ respectively.
