Question

the area of the square is Same as area of the rectangle length of the rectangle in 12cm and breadth is 4 cm find the side of the square​

Answer 1

Answer:

Given:

Side of Square =12 cm

∴ Area of square =12×12

=144 cm

2

Now,

let the breadth of rectangle be x

∴ Area of rectangle =Length×breadth

=16×x

According to question,

Both the areas are equal. So,

⟹16x=144

⟹x=

16

144

=9cm

∴breadth(x)=9 cm

Now ,

Perimeter of rectangle =2(Length+breadth)

=2(16+9)

=50cm

Answer 2

Answer:

Side of square is 4(3^½) cm.

Step-by-step explanation:

Given, Area of rectangle = Area of square

Length of rectangle is 12 cm and breadth is 4 cm

Solution, Area of rectangle = l × b

= 12 × 4

= 48 cm²

Since, Area of rectangle = Area of square

Therefore, Area of square = 48 cm²

(Side)² = 48

Side = 48^½

Side = 4(3^½) cm
