Question

Given that the points (-2, 10), (5, 10), (5, 1), and (-2, 1) are vertices of a rectangle, how much longer is the length than the width?

Answer 1

A

Explanation:

Answer 2

The length is 2 units longer than the width

Explanation:

Let

`A(-2, 10), B(5, 10), C(5, 1), D(-2, 1)`

Using a graphing tool

Plot the vertices of the rectangle

See the attached figure

we know that

AD=BC ------> the length

AB=DC ------> the width

Find the length

`L=10-1=9\ units`

Find the width

`W=5-(-2)=7\ units`

Find the difference

`9\ units-7\ units=2\ units`

therefore

The length is 2 units longer than the width
