Question

Express the area of the rectangle in term of x

Answer 1

Answer:

Area = $12-\frac{4}{35}x$

Step-by-step explanation:

Length of the given rectangle 'l' = (15 - $\frac{1}{7}x$)

Width of the given rectangle 'w' = $\frac{4}{5}$

Area of the rectangle = lw

                                    = $\frac{4}{5}(15-\frac{1}{7}x)$

                                    = $\frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x$

                                    = $12-\frac{4}{35}x$

Therefore, expression that defines the area of the given rectangle will be,

Area = $12-\frac{4}{35}x$
