Question

Because the lid of a marker is wider than the marker itself, a set of markers can be packaged in a container that is in the shape of a trapezoid instead of a rectangle.

Answer 1

Answer:10

Step-by-step explanation: I did this on a test and got it correct

Answer 2

The difference in area between the trapezoid and the rectangle is 10 in²

Explanation:

The dimensions of the trapezoid are given as follows;

Base 1, a = 12 in

Base 2, b = 10 in

Height, h = 10 in

Area, A of trapezoid;

`A = (a+b)/(2) h = (10+12)/(2) 10 = 110 in^2`

The dimensions of the rectangle are given as follows;

Base = 12 in

Height = 10 in

Area, A of rectangle;

Base × Height = 12 × 10 = 120 in^2

Therefore, the difference in area between the two packages is found as follows;

Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²

The difference in area between the trapezoid and the rectangle = 10 in².
