Question

The shape in the figure is constructed from several identical squares. If the side of each square is 1 unit, what is the area and the perimeter of the shape?

Answer 1

• area: 7 units²
• perimeter: 14 units

Explanation:

You can count the unit squares to find the area. There are 7 of them, so the area is 7 square units.

There are 4 unit lengths along the bottom perimeter, 3 up each side (for a total of 6), and 4 more unit lengths across the tops of the squares in the figure. The perimeter is a total of 4+6+4 = 14 units.
