A piece of string is 108cm long. If the string is to form length |
|
Answer» Answer: SOLUTION:- The string length is the PERIMETER of the shape. ∴ For each case, perimeter=30cm (i) Square A square has all the side equal. Perimeter=4×(side of square) ∴side of square= 4 perimeter
= 4 30
=7.5cm Hence, length of each side if the string is used to FORM a square will be 7.5 cm. (ii) Equilateral triangle An equilateral triangle has three equal sides. Perimeter=3×(side) ∴side= 3 perimeter
= 3 30
=10cm Hence, length of each side if the string is used to form an equilateral triangle will be 10 cm. (iii) Regular hexagon A regular hexagon has six equal sides. Perimeter=6×(side) ∴side= 6 perimeter
= 6 30
=5cm Hence, length of each side if the string is used to form a regular hexagon will be 5 cm. Step-by-step explanation: Hope it helps you dear.. |
