Question

The figure shown is made up of a square and a triangle. Express the area of the figure in terms of y.

Answer 1

`y^2+2y`

Explanation:

The area of a square can be found by
`s^2` and the area of a triangle can be found by
`(1)/(2)b*h`.

The area of the square with side length y is
`y^2`.

The area of the triangle with the base 4 and height y is
`(1)/(2)4*y = 2y`

Adding the areas together gives
`y^2+2y`
