or
А
square of side 39 cm.​

Answer 1

Answer:

The square has a larger area than the rectangle..

Step-by-step explanation:

First Let's find the area of rectangle ..

Length = 42cm

Breadth = 28cm

Area of Rectangle= L x B

                             = 42 x 28

                             = 1176

Now let, find the area of square.

Area of Square = Side x Side

                         = 39 x 39

                          = 1521

∴ The square has a larger area than the rectangle..

Answer 2

Answer:

The square has a larger area by 350 cm

Step-by-step explanation:

Length of rectangle = 42 cm

Breadth of rectangle = 28 cm

So, Area of rectangle = Length×Breadth

= 42×28 cm

= 1,176

Side of square = 39 cm

Area of square = side²

= 39×39 cm

= 1,521 cm

So, 1,521 - 1,171 = 350 cm
