Question

find the perimeter of a rectangle whose sides are a) 7m 50cm and 5m 25cm​

Answer 1

Sides: 7m 50cm and 5m 25 cm

= 7 + 0.5 m and 5 + 0.25 m

= 7.5 m and 5.25 m

So,

Perimeter of rectangle = 2(7.5 + 5.25)

= 2( 12.75)

= 25.5 m^2

Answer 2

Step-by-step explanation:

Convert the values into cm

$7m \: 50cm = 750 \: cm$

$5m \: 25 \: cm =525cm$

$perimeter \: of \: rectangle = 2(l + b) \\ l = 750 \: cm \\ b = 525 \: cm$

$= 2(750 + 525) \\ = 2(1275) \\ = 2550 \: cm$
