what is the perimeter of the trapezoid? units

Explanation:

Step1: Assume grid - unit length

Assume each grid square has a side - length of 1 unit.

Step2: Count side - lengths

Count the lengths of each side of the trapezoid by counting the number of grid units along each side. Let's assume the lengths of the sides are (a), (b), (c), and (d). After counting, say (a = 5), (b = 3), (c = 4), (d = 3).

Step3: Calculate perimeter

The perimeter (P) of a trapezoid is (P=a + b + c + d). So (P=5 + 3+4 + 3). [P=15]

Answer:

15
