Question

Each side of a square field measure 21m.Adjacent to this field there is a rectangular field having its sides in the ratio 4:3.If the perimeters of both the field are equal.Find the dimension of the rectangular of the rectangular field.​

Answer 1

Answer ⤵️

Perimeter of the square field= 4×side

= 4×21

=84m²

Let the field's side be 4x and 3x.

Perimeter of the rectangular field= 2(4x+3x)

84=8x+6x

84=14x²

x=84/14

x=6

So actual length=4x=4×6=24

breadth= 3x=3×6= 18
