The length of a side in an equilateral triangle is 5 inches. find the area of the triangle.

5√3 square inches
6.25√3 square inches
12.5√3 square inches

Option B :   square inches.

Step-by-step explanation:

The area of an equilateral triangle is given by :

A =

Where, a is the side of the triangle.

Here in the question, we have been given the side of the triangle as 5 inches.

So, area is :

Simplifying this we get,

Area = square inches.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
