Question

breadth = ? , length = 20mm , perimeter = 50mm​

Answer 1

Answer:

length=20mm

perimeter = 50mmperimeter=50mm

p = 2(l + b)p=2(l+b)

50 = 2(20 + b)50=2(20+b)

(50}{2} = 20 + b 250

=20+b

b = 25 - 20b=25−20

b = 5b=5

therefore b = 5mm∴b=5mm

Answer 2

Answer:

bredth = 5

Step-by-step explanation:

bredth = perimeter/2-length

bredth = 50/2-20

bredth = 25-20

bredth = 5 (Ans).
