The area of the equilateral triangle is 20√3 cm² whose each side is 8 cm. Is the given statement true or false and justify your answer.
Solution:
Given, area of the equilateral triangle is 20√3 cm²
Length of each side = 8 cm
We have to determine if the given statement is true or false.
Area of equilateral triangle = √3/4 (side)²
= √3/4 (8)²
= √3/4 (64)
= √3(16)
Area = 16√3 cm²
Therefore, the given statement is false.
✦ Try This: Write True or False and justify your answer: The area of the equilateral triangle is 30√3 cm² whose each side is 6 cm.
Given, area of the equilateral triangle is 30√3 cm²
Length of each side = 6 cm
We have to determine if the given statement is true or false.
Area of equilateral triangle = √3/4 (side)²
= √3/4 (6)²
= √3/4 (36)
= √3(9)
Area = 9√3 cm²
Therefore, the given statement is false.
