Question

find the perimeter and area of a rectangle having length- 8 m breadth- 9 dm

Answer 1

8 m = 900 cm = Length

9 dm = 90 cm = Breadth

Formula:

Perimeter = 2 ( l + b )

Area = lb

Solution:

Perimeter = 2 ( 900 + 90 )

Perimeter = 2 ( 990 )

Perimeter = 1,980 cm

Area = 900 × 90

Area = 81,000 sq.cm
