Question

Wha is the area of a rectangle with vertices at (4, 3), (11, 3), (11,9), and (4, 9)?

Answer 1

42 units^2.

Explanation:

We are given that it is a rectangle so its area is the product of the length of adjacent sides.

Length of the horizontal line = 11 - 4 = 7 units ( from the first 2 points) and the length of an adjacent side is 9 - 3 = 6 units (from the second and third points).

Area = 7 * 6 = 42.

Answer 2

area of rectangle = 42

Explanation:

area of rectangle = length × width

= 7 × 6

= 42
