Asteel company is making flat rectangular frames as a part of a new product they are launching. each frame will be cut out of a piece of steel and will have a final area as close to 28 cm2 as possible. the width of the frame needs to be uniform throughout. the inside dimensions of the frame must be 11 cm by 6 cm. complete the equation that models the above situation, and find the width of the frame, x

x = 0.76

Step-by-step explanation:

We can write the area of steel before it is cut as:

Area =

Expanding it by multiplying the brackets to get:

Area =

Area  area of steel before cutting =

Then we need the area of steel after 11*6 inside dimensions are cut out:

This area should be close to 28 cm, hence the equation becomes:

Moreover, plotting the graph gives us a value of x = 0.76.
