Question

If the area of an equilateral triangle is
25 under root of 33 sq.cms, then find its side​

Answer 1

Answer:

We know that, the area of equilateral triangle is given by 

We know that, the area of equilateral triangle is given by A=43a2, where a is side of triangle 

We know that, the area of equilateral triangle is given by A=43a2, where a is side of triangle We are given that area of equilateral triangle is A=253 sq.cms.

We know that, the area of equilateral triangle is given by A=43a2, where a is side of triangle We are given that area of equilateral triangle is A=253 sq.cms.So, 253=43a2

We know that, the area of equilateral triangle is given by A=43a2, where a is side of triangle We are given that area of equilateral triangle is A=253 sq.cms.So, 253=43a2a2=3253×4=100

We know that, the area of equilateral triangle is given by A=43a2, where a is side of triangle We are given that area of equilateral triangle is A=253 sq.cms.So, 253=43a2a2=3253×4=100a=10 cms

Answer 2

Answer:

10 cm

Step-by-step explanation:

We know that, the area of equilateral triangle is given by

A= √3/4a²

, where a is side of triangle

We are given that area of equilateral triangle is A=25√3 sq.cms

so, 25√3=√3/4a²

a²=25√3*4/√3

a²=100

a=10cms
