Question

Find the area of the rhombus.

Answer 1

You can see that the rhombus is cut into 4 right triangles each with a hypotenuse of 25 and a leg of 15. Find the area of a triangle and multiply by 4 to get the area.

Answer 2

To find the missing leg of the right triangle use the formula: a²+b²=c² where c is the hypotenuse:
a = 15 , c = 25
15² + b² = 25²
b² = 400
b = 20
Then find the area of triangles
