Answer 1

please mark brainliest answer.

Answer 2

Answer:

let l be the length of the rectangle, b its breadth and p its perimeter.

Then, l = 102cm and P = 360cm

Perimeter of the rectangle = 360cm

$2(l \: + \: b) = 360cm \\ \\ 2(102 \: cm + b) = 360cm$

(102 cm + b) = 360/2 cm = 180cm

b = (180-102) cm = 78 cm

✅ hence the breadth of the rectangle is 78 cm.
