Question

What is the area of the figure at the right. Justify your procedure?

Answer 1

area of the square : s × s ⇒ 3 × 3 = 9 in.

the figure in the left is a rectangle

and opposite sides of a rectangle are equal ... so , the side on the top is 3.1

∴ 6.1 - 3.1 = 3

so the top of the figure on the right is 3 ...

area of square = s×s

=3×3= 9 in.

Answer 2

The area of the smaller figure would be found by multiplying its base length by its height. The height is explicitly provided while the base length is not.

To find the base length of the smaller figure, subtract the shorter length on the bottom (3.1 inches) from the total length on top (6.1 inches).

6.1 - 3.1 = 3

3 * 3 = 9

Answer:

The area of the figure at the right is 9 square inches.
