Question

Find the length of a rectangle whose perimeter is 90 cm and breadth is
20 cm.

Answer 1

Answer:

The value of length is 25

Step-by-step explanation:

perimeter = 90 cm

breadth = 20 cm

perimeter = 2( length + breadth)

90 = 2( length + 20)

length + 20 = 90/2

length = 45 - 20

length = 25 cm

Answer 2

Answer:

25 length

Step-by-step explanation:

perimeter =2(l*b)

90=2(l*20)

90=2*20,2*length

90=40,2length

90-40/2=length

50/2=length

25=lenght
