How to find the area of a rhombus if one of the sides is 4 cm?

To solve this task, you need to find the area of the rhombus;

Consider this task and analyze it;

According to the condition of the assignment, we are given a rhombus with a side of four centimeters, and the acute angle of the rhombus is 60 °.

We write the formula for the area of a rhombus through the angle and side of the rhombus;

S = a2 * sinx;

Where a is the side of the rhombus, sinx is the sine of the angle of the rhombus;

With this formula, we find the value of the sine of the angle;

sinx = sin60 ° = √3 / 2;

Substitute the obtained sine data into the area formula and roll the expression

S = 42 * √3 / 2;

S = 16 * √3 / 2;

S = 8√3 cm2.
