The student is not correct (see the procedure)

Step-by-step explanation:

we know that

A deck can be broken into a rectangle and triangle

so

The area of the deck is equal to sum the area of a rectangle plus the area of a triangle

Find the area of rectangle

Find the area of triangle

Adds the areas

therefore

The student is not correct

the answer will be b x² +x-1
