Given: △ABC AB=BC=AC Area of △ABC= 25 3 4 cm2 Find: The perimeter

15 cm

Step-by-step explanation:

The area of an equilateral triangle is:

, where a is the length of one side.

We can find the value of a (the length) by:

a = 5, so the side length of this triangle is 5 cm.

The perimeter of an equilateral triangle will be 3 times the length.

Hope this helped!

step-by-step explanation:

infinity is the answer

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
