The length of AB is (x + 4) cm, and the values of a and be are a = 10 and b = 4 respectively for rectangle ABCD.

<h3>What is defined as the rectangle?</h3>
  • A rectangle is a category of quadrilateral, a two-dimensional shape with four sides as well as four vertices.
  • The rectangle's four angles are all right angles but rather equal to 90 degrees.

A rectangle is a quadrilateral with opposite sides that are equal and parallel.

A rectangle's area is given by:

Area = length * width

From the diagram:

Length of AB = x + 4

Length of BC = x + 6

The area of the rectangle ABCD is equal to the sum of the lengths of AB and BC.

Area of rectangle ABCD = Length of AB × Length of BC

28 = (x + 4)(x + 6)

x² + 10x + 24 = 28

x² + 10x = 4

Compare with x² + ax = b, values of a and b are obtained as;

a = 10, b = 4

As a result, the length of AB is (x + 4) cm, and the values of a and be are a = 10 and b = 4 respectively.

The correct question is -

The area of rectangle ABCD is 28 cm^2

a) What is the length of side AB in terms of x?

b) If the area of rectangle ABCD is 28cm^2

we can show that x2 + ax=b

a and b are integer values.

Work out the values of a and b.

If you would like to solve the equation 16 = (- 5 + z) / 4, you can do this using the following steps:

16 = (- 5 + z) / 4       /*4
16 * 4 = - 5 + z
16 * 4 + 5 = z
 z = 69

The correct result would be a. 69.
