The inequality which makes the function have two real roots is; m > -1/5.

<h3>What is the inequality which makes the function have two real roots?</h3>

It follows from the task content that the required inequality may be determined by subjecting the determinant to greater than 0 as follows;

D > 0

b² - 4ac > 0

(2)² - 4(m)(-5) > 0

4 +20m > 0

20m > -4

m > -4/20

m > -1/5

Step-by-step explanation:

firstly we must divide the shape like this

and the area of first rectangular is 27 m²( 9m × 3m)

then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)

the third rectangular's area is 10 m² ( we found it from 9-4)

Total is 27+48+10=85 m²

hope it helps
