breadth = 20 cm
length =??
if perimeter is 92 cm and breadth is 20 cm what is lenght ??

Answer 1

Answer:

l= 26

mark me as brainliest

Answer 2

perimeter = 92 cm

breadth= 20 cm

length = a

P=2(l+b)

P=2(a+20)

P= 2a + 40

92 cm = 2a + 40

92 - 40 = 2a

52 = 2a

52/2 = a

a = 26

so length is 26cm
