Question

Mikel has a poster that she wants to copy onto a mural at school. The dimensions of the poster are shown below.

If Mikel doubles the dimension of the poster, what will be the area in square feet, covered by the mural?

Answer 1

The area of the poster would be 20ft².

Explanation:

• First, double both the length and the width.

LENGTH : 2 x 2 = 4

WIDTH : 2.5 x 2 = 5

• Use these new dimensions to work out the area

4 x 5 = 20ft²
