Question

The length of a rectangle is 15cm more than the breadth. Iths perimeter is 150 CM. Find it's length and breadth​

Answer 1

Answer:

please mark me as brainliest

Step-by-step explanation:

length is equal to 15 + breadth

perimeter us equal to 150

l+b is equal to 150

15+b+b is equal to 150

15 +2b is equal to 150

150-15 is equal to 2b

135 is equal to 2 b

b is equal to 135/2

Answer 2

Answer:breath=60cm

Step-by-step explanation:

perimeter of a rectangle =2(l+b)

So breath=?

length =15cm

perimeter =150cm

perimeter =2(length +breath)

150=2(15+breath)

150÷2=(15+breath)

75=15+breath

75-15=breath

60=breath

PROVE=

perimeter=2(l+b)

perimeter =2(15+60)

perimeter =150
