(a) |
(b) |
(c) |
(d) |
Answer:
(a) Perimeter \[=4\times side\] \[=4\times 25\text{ }cm\] \[=100\text{ }cm\] (b) Perimeter \[=2\times (length+breadth)\] \[=2\times (40\,\,cm+10\,\,cm)\] \[=2\times 50\text{ }cm\] \[=100\text{ }cm\] (c) Perimeter \[=2\times (length+breadth)\] \[=2\times (30\,\,cm+20\,\,cm)\] \[=2\times 50\text{ }cm=100\text{ }cm\] (d) Perimeter\[=30\text{ }cm+30\text{ }cm+40\text{ }cm\] \[=100\text{ }cm\] It is clear that all the figures have same perimeter of length 100 cm.
