NOTE - answer in units ​

Answer 1

Answer:

x/5 + y/a = 1 area of ∆ AOB = 15 sq units

to find the value of a

Equation of given line is on intercept form

hence a = y intercept = OA

put y = 0 in the equation to get the value of x = OB

x/5 + 0/a = 1

x/5 = 1

x = OB = 5 units

now area of ∆ AOB = 1/2"OB*OA

15 = 1/2*5*OA

therefore OA = a = (15*2)/5

=> 6

therefore value of a = 6 units
