Hello I need help with this question

Rhombus

Step-by-step explanation:

Apply the formula for finding distance using coordinates to find the length of the sides of the parallelogram

Given the coordinates as;

P(6,-6) , Q(1,1),R(-6,6),S(-1,-1)

Finding the lengths

The formula to apply is;

For PQ  where you have : P(6,-6) , Q(1,1)

You can also apply the Pythagorean relationship to get the leg distance and calculate the hypotenuse .For example to get the length of QR ;

QR² = 7²+5²

QR = √49+25

QR = 8.60

You notice all sides are equal , 8.60 units

You also notice the opposite angles are equal

This is a rhombus

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
