Answer:
100
Step-by-step explanation:
A rhombus is split into four right triangles
The base of one is 5 and the hypontenuse is 10
So remember x^2y^2=z^2
5^2=25
25+y^2=100
Ok so y is between 8 and 9 so lets just use 8 first
5*8*1/2=20
there are 4 triangles so 20*4=80
now same thing with 9
5*9*1/2=22.5
22.5*4=90
your answer is between 80 and 90
btw i might have gotten the answer wrong but idk if u were supposed to have an exact answer and also idk if the "10" was the hypontheses but since u were probably offline i answered it
