Question

an equilateral triangle has sides of length 15 cm, correct to the nearest centimetre. calculate the upper bound of the perimeter of the triangle​

Answer 1

Step-by-step explanation:

Given an equilateral triangle has sides of length 15 cm, correct to the nearest centimetre. calculate the upper bound of the perimeter of the triangle

• So all the sides are equal in an equilateral triangle.
• So according to the question each side is 15 cm
• So we need the accuracy to nearest cm
• So 1 cm / 2 = 0.5 cm
• So upper bound will be 15 + 0.5 = 15.5 cm
• So perimeter of the triangle of upper bound will be  
•          15.5 + 15.5 + 15.5 = 46.5 cm
