1.	. If the perimeter of an equilateral triangle is 60 m, then the area is: a. 10√3 sq m b. 15√3 sq m c. 20√3 sq m d. 100√3 sq m
Answer» ANSWER: d)100√3m^2 Step-by-step explanation: Formula for perimeter of EQUILATERAL triangle=3a, where 'a' is LENGTH of each side 3a=60 a=20m Formula for area of equilateral triangle=√3/4×a^2 √3/4×(20)^2 √3/4×400 100√3m^2

. If the perimeter of an equilateral triangle is 60 m, then the area is: a. 10√3 sq m b. 15√3 sq m c. 20√3 sq m d. 100√3 sq m

Answer»

d)100√3m^2

Step-by-step explanation:

Formula for perimeter of EQUILATERAL

triangle=3a, where 'a' is LENGTH of each side

3a=60

a=20m

Formula for area of equilateral

triangle=√3/4×a^2 √3/4×(20)^2 √3/4×400 100√3m^2
