Question

The area of a rectangular field is 19.25 M it is 30.8 cm wide find its perimeter

Answer 1

Let the length be x cm

19.25m² = 19.25*100 = 1925cm²

Area of rectangle =1925 cm²

Length*breadth=1925

x*30.8=1925

x=1925/30.8

x=62.5cm

. '. Length = 62.5cm

Perimeter of a rectangle

= 2(length+breadth)

=2(62.5+30.8)

=2*93.3

=124.1cm
