​

Answer 1

Step-by-step explanation:

the length of the rectangle is =15cm

if the breadth of the rectangle is=84cm

(lxb)

84

×15

=1260

Answer 2

Step-by-step explanation:

let meet of ratio of demensions to be x

Means length be 2x and breath be x

=) p = 2 ( l+b)

= 84 cm = 2 ( x +x )

= 84 cm = 2× 3×

= 84 cm= 6x

= 84 cm /6 = x

= 14 cm

hence length = 2 × 8 cm = 16 cm

and breath = 1× 8 cm = 8cm
