Use the Distance Formula to find the distance between each pair of points. Round to the nearest tenth if necessary. 5. P(1, 1), Q(–1, –1)

6. E(1/2,4 1/4),F(5,-1/2)

Given:

The pair of points.

5. P(1, 1), Q(–1, –1)

6.

To find:

The distance between the pair of points.

Solution:

Distance formula:

5.

The distance between the pair of points P(1, 1) and Q(–1, –1) is:

Therefore, the distance between P and Q is .

6.

The distance between the pair of point is:

On further simplification, we get

Therefore, the distance between E and F is 6.5 units.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
