**4. The figure below is composed of seven congruent squares. The area is 43.75 cm**^{2}**. Calculate its perimeter. **

^{2}

**A = area**

**P = perimeter**

**A = 43.75 cm**

**7 congruent squares**

**14 congruent squares = P**

**First divide the area of the shape by the number of congruent squares to get the area of one square.**

**Find the square root of the area of one square to get the side length.**

**Multiply the side length of one square by the number of sides to get the perimeter.**

**Algebraic Way**

**The perimeter of the shape is 35 cm.**
