Question

5. Find the perimeter of the rectangles whose :
(1) length = 25 cm, breadth = 16 cm
(ii) length = 35 cm, breadth = 28 cm
(iii) length = 25.5 m, breadth = 20.5 cm
​

Answer 1

$perimeter \: of \: rectangle \: = 2 + \times (length + breadth$

$1) \: Length \: = 25 \: cm \: \\ breadth \: = 16 \\ 2 \times( 25 + 16 ) \: = \: 82$

$2) \: length \: = 35 \\ breadth = 28 \\ 2 \times (35 + 28) = 126$

$3) \: length = 25.5 \\ breadth \: = 20.5 \\ 2 \times (25.5 + 20.5) = 92.0$
