Correct Question:
- The breadth of a rectangular garden is 2/3 of its length. If its perimeter is 40 m, find its dimensions.
Answer:
- The length and breadth of the garden are 12 m and 8 m respectively.
Step-by-step explanation:
Given that:
- The breadth of a rectangular garden is 2/3 of its length.
- The perimeter of the rectangular garden is 40 m.
To Find:
- The dimensions of the rectangular garden.
Let us assume:
- The length of the rectangular garden be x.
Then,
- The breadth of the garden will be 2x/3.
As we know that:
- Perimeter of rectangle = 2(length + breadth) units
Substituting the values,
Solving the bracket,
Opening the bracket,
Multiplying RHS,
Transposing 3 from RHS to LHS and changing its sign,
Multiplying LHS
Transposing 10 from RHS to LHS and changing its sign,
Dividing LHS,
Hence,
- x = 12
Therefore,
- Length of the garden = x = 12 m
- Breadth of the garden = 2x/3 = (12 × 2)/3 = 8 m
