Question

the length and breadth of a rectangle is are 425 dm anf 300 dm respectively. find the area and perimeter of rectangle in mm

Answer 1

${\large{\boxed{\boxed{\boxed{\boxed{\mathsf{\red{1 \ dm \ = \ 100 \ mm}}}}}}}}$

Given :

Length = 425 dm = ( 425 × 100 ) mm = 42500 mm

Breadth = 300 dm = ( 300 × 100 ) mm = 30000 mm

Area of the rectangle = Length × Breadth

= 42500 × 30000

= 1275000000 mm²

Perimeter of the rectangle = 2 ( Length + Breadth )

= 2 ( 42500 + 30000 )

= 145000 mm
