Answer 1

Answer:

15m/15 मी

Step-by-step explanation:

Perimeter of the rectangle = 100 m

Length of the rectangle= 35 m

Breadth of the rectangle= ?

Solution :

Perimeter of a rectangle =2( length + breadth )

Therefore, 100=2(35+b)

Therefore,100=70+2b

Therefore,100-70=2b

Therefore,2b =30

Therefore ,b = 30/2

Therefore,b =15metres

Answer 2

Answer:

option (a) 15m

Step-by-step explanation:

perimeter of the rectangle =2(l+b)

given perimeter =100m,breadth=35

100=2(35+b)

100=70+2b

2b=100-70

2b=30

b=30/2b=15
