Question

the perimeter of a rectangular pool is 100 metre and its length is 30 m find its breadth​

Answer 1

Step-by-step explanation:

2(l+b) = 100

l+b=50

B= 20 CM

Answer 2

question :-

the perimeter of a rectangular pool is 100 metre and its length is 30 m find its breadth ??

formula :-

⇢ perimeter = 2( length + breath)

solution :-

perimeter = 2( l + b )

$⇢ \: 100 = 2(30 + x)$

$⇢ \: 30 + x = \cancel\dfrac { 100} { 2 }$

$⇢ \: 30 + x = 50$

$⇢ \: x = 50 - 30$

$⇢ 20$

so therefore our required answer is breath = 20m
