This one too
solve for x
z=xy

x=z/y divide by y on both sides

Here's the steps.

Flip the sides, because it's neater.  xy=z

divide both sides by y.   xy/y=z/y

Cancel out the y's on the first side   x=z/y

The answer is x=z/y

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
