Answer 1

$\huge\boxed {\texttt {\fcolorbox {red} {aqua} {SOLUTION ;}}}$

$<b ><i >$ It is given that two squares are placed side by side to form a rectangle.

Length of one side of the square = 20 cm
So, all the sides of the square are equal.

Therefore, the total length of the rectangle, l = 20+ 20 = 40 cm

The breadth will be equal to the side of the square, b = 20 cm

We know that, Perimeter of a rectangle = 2(l + b) = 2 ( 40 + 20) = 2 × 60 = 120 cm

Answer 2

 It is given that two squares are placed side by side to form a rectangle.

Length of one side of the square = 20 cm
So, all the sides of the square are equal.

Therefore, the total length of the rectangle, l = 20+ 20 = 40 cm

The breadth will be equal to the side of the square, b = 20 cm

We know that, Perimeter of a rectangle = 2(l + b) = 2 ( 40 + 20) = 2 × 60 = 120 cm
