Answer 1

Answer:

l=52m,b=25m

Step-by-step explanation:

let the breadth be x

then according to the equation

2×(l+b)=154&l=2x+2

2×(2x+2+x)=154

3x+2=154/2=77

3x=77-2=75

x=75/3=25

therefore breadth=x=25m

length=2x+2=(2×25)+2=50+2=52m

Answer 2

p=154m

l=(2m+2b)

b=b

p=2(l+b)

154=2[(2m+2b)+b]

154=4m+3b

154-4=3b

150/3=b

50m

l=104

b=50
