Step-by-step explanation:
Given:-
Side of Square Garden = 18 cm
Length of Rectangular Garden = 12 cm
Perimeter of Rectangular Garden = Perimeter of Square Garden
→ Perimeter of Rectangular Garden = 4 × 18 cm = 72 cm
→ 2 (length + breadth) = 72 cm
→ 2 (12 cm + b) = 72 cm
→ 24 cm + 2b = 72 cm
→ 2b = 72 cm - 24 cm
→ 2b = 48 cm
→ b = 48 cm/2 = 24 cm
Now, length and breadth of the Rectangular Garden are 12 cm and 24 cm respectively.
Area of Rectangular Garden = (length × breadth)
= (12 × 24) cm² = 288 cm²
Therefore, the area of the rectangular garden is 288 cm².
