Give the coordinates of the focus and the equation of the directrix with the equation

Well from what i see this equation isn't a point at all, however it does start at (0,0)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to
