let the breadth =×
and the length of rectangle =2×
given , perimeter =300
2(l+b)=300
2(×+2×)=300
2(3×)=300
6×=300
×=300/6
×=50
therefore , the breadth of rectangle =50
and it's length =2×=2×50=100
and the length of rectangle =2×
given , perimeter =300
2(l+b)=300
2(×+2×)=300
2(3×)=300
6×=300
×=300/6
×=50
therefore , the breadth of rectangle =50
and it's length =2×=2×50=100

Step-by-step explanation:
Given -:
- Length of a rectangular park is twice its breadth
- Perimeter of a rectangular park = 300m
To Find -:
- Length and breadth of a rectangular park
Assuming -:
Let us assume breadth as x
Then,
Length = 3x
Explanation -:
Length = 2x = 2 × 50 = 100m
Breadth = x = 50m
Verification -:
Perimeter = 2(Length + breadth)
→ 2(100 + 50)
→ 2(150)
→ 300m
Hence, proved.
