Answer 1

Answer:

here is the answer of your question dude

Answer 2

Answer:

CD= 8 cm

Step-by-step explanation:

By combining first and second rectangle

$L= 6cm$

Area$=12+18$

$=40 cm^{2}$

Area$= L\times B$

$6\times B = 30$

$B=\frac{30}{6} = 5cm$

Now, by combining second and third rectangle

Breadth$=\frac{30}{6}=5 cm$

Length$= ?$

Area$= 18+22=40cm^2$

$L\times B= 40$

$L\times 5 =40$

$L= 8 cm$

$\therefore CD=8cm$

About rectangle:

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

The rectangle's characteristics are listed below:

• There are four vertices and four sides.

• Every vertex has an angle of 90 degrees.

• Equal and parallel sides are on the opposing sides.

• Intersect each other diagonally

• The perimeter is equal to double the length plus width of the object.

• the product of its length and width determines its area.

• It has four right angles and is a parallelogram.

• All inner angles added together equal 360 degrees.
