Question

A rectangle on a coordinate plane has vertices Q(-1,1), R(6, 1), S(6-8), and T(-1,-8). What are the dimensions of the
rectangle?
.
The base is 6 and the height is 9.
The base is 9 and the height is 6.
The base is 7 and the height is 9.
The base is 9 and the height is 7.

Answer 1

Answer:

the base length of the triangle is 4 units, u can count that. and the height of triangle is 2 units, thats the dotted line one. and the equation of triangle area is (length x height) divided by 2so in this case it'll be (4x2) /2=4 square units.

Answer 2

Answer:

The base is 7 and the height is 9

Step-by-step explanation:

vertices Q(-1,1), R(6, 1), S(6-8), and T(-1,-8)

If you look at the coordinates, you will notice that Q and R lie on line y = 1

and S and T lie on the line y = -8

so  line QR || line ST

that means the height of this rectangle is  |1 - -8| = 9

the  length must be  from point Q to R

length = |-1 - 6| = 7

dimension is  7 by 9
