Question

what is the perimeter of the figure shown if the slanted side is 5.3 units long?

Explanation:

Step1: Count horizontal side lengths

By counting grid - squares, the horizontal bottom side is 8 units long and the top horizontal part is 6 units long.

Step2: Count vertical side lengths

The two vertical side lengths are both 3 units long.

Step3: Identify slanted side length

The slanted side length is given as 5.3 units.

Step4: Calculate perimeter

Perimeter = sum of all side lengths. So, Perimeter = 8 + 6+3 + 3+5.3 = 25.3 units.

Answer:

25.3 units
