1.	The perimeter of a rectangle is 150 cm . The length is 15 more than breadth
Answer» We know that the PERIMETER of a rectangle is 2(L+B) = 150cm Let l be the length and b be the breadth. We are given the INFO that length is 15cm more than breadth. So, l=b+15 So, 2(b+15+b)=150 2(2b+15)=150 4b+30=150 4b=120 b=120/4=30 So l=b+15 l=30+15 l=45cm SO, l=45cm b=30cm

The perimeter of a rectangle is 150 cm . The length is 15 more than breadth

Answer»

We know that the PERIMETER of a rectangle is 2(L+B) = 150cm

Let l be the length and b be the breadth.

We are given the INFO that length is 15cm more than breadth.

So, l=b+15

So, 2(b+15+b)=150

2(2b+15)=150

4b+30=150

4b=120

b=120/4=30

So l=b+15

l=30+15

l=45cm

SO,

l=45cm

b=30cm
