Question

a wire is is in the shape of the rectangle whose dimension are 12cm×9cm if it is rebent is the form of the square find the side of square

Answer 1

Answer:

Perimeter of rectangle= 2(l+b)

=2(12+9)

=42cm

since perimeter of square= perimeter of rectangle

therefore, side*4=42

so, side=42/4=10.5 cm

Answer 2

perimeter of rectangle = 2(l+b)

2(12+9)

=2(21)

42cm

since, perimeter of square = perimeter of rectangle

4×side= 42cm

4×X=42cm

x= 42/4 cm

x=10.5cm
