(a)The length of DA  = 3.2 units (app.)

(b) The length of CD  = 6.32 units

(c)Area of the rectangle =  20.2 sq units.

Step-by-step explanation:

Here the coordinates of the rectangle are given as

A(-3,0), B(3,2), C(4,-1) and D(-2,-3).

DISTANCE FORMULA: For two points P(a,b) and Q(c,d)

The length of PQ =

(a)The length of DA  =

Hence, the length of DA  = 3.2 units (app.)

(b) The length of CD  =

Hence, the length of CD  = 6.32 units

(c)Now, area of the rectangle = LENGTH X WIDTH

                                                  = Length of DA x Length of CD

                                                  = 3.2 units x 6.32 units  = 20.2 sq units.

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
