Question
Can you make a rectangle with a still longer boundary? I made a rectangle 1 cm wide and 80000 m long. Imagine how long that boundary will be!!! With that much gold wire I can become a king!
Solution
Perimeter = 2(length + breadth)
= 2(80000 m + 1 cm)
= 2(80000 m + 1/100 m)
= 2(80000 m + 0.01 m)
= 2 x 80000.01 m
= 16000.02 m
