Question

Find the breadth of rectangle whose perimeter is 60 m and length 18 m
​

Answer 1

Answer:

Perimeter = 2( lenght+ breadth)

60=2(18+ breadth)

Breadth=12

Answer 2

Answer:

12m

Step-by-step explanation:

let the b of the rectangle be x

$perimeter \: of \: rectangle \: = 2(l + b) \\ 60m = 2(18m + b) \\ 60m = 36m + 2b \\ 60 m - 36m = 2b \\ - 2b = - 24m \\ b = \frac{24}{2} \\ = 12m$
