Question

find the area of this irregular shape.
begin by dividing this shape into smaller rectangles.
how many rectangles do you see?
a) 2
b) 3
c) 1
note: a square is a special type of rectangle
(the shape in the image has dimensions labeled: 7 cm, 4 cm, 16 cm, 7 cm, 7 cm)

Explanation:

Step1: Analyze the shape

The irregular shape can be divided into three rectangles: the left vertical rectangle, the middle horizontal rectangle, and the right vertical rectangle (or by observing the two indentations and the main structure, we can see three rectangular parts when dividing properly).

Step2: Confirm the number

By visually inspecting the shape and dividing it into smaller rectangles as suggested, we can identify three distinct rectangles (the left tall rectangle, the middle horizontal one, and the right tall rectangle, considering the indentations as part of the division into three rectangles).

Answer:

B) 3
