Answer 2

Hello !! Your require answer is ,

Length of a rectangle = 9 hm ( 90 dam )

9 hmBreadth of a rectangle = 7 dam

( To find area and perimeter first uh will convert

hm to dam )

(so, no. of hm × 10 = no. of dam

9 × 10 = 90 dam )

Area = L × B

Area = L × B = 90 × 7

Area = L × B = 90 × 7 = 630 dam²

Perimeter = 2 ( l + b )

= 2 ( 90 + 7 )

= 180 + 14

= 194 cm

Hope it helps uh!!
