Question

what is the perimeter? question 3 of 8 19 cm 15 cm 20 cm 26 cm 6 cm 4 cm 2 cm 3 cm

Explanation:

Step1: Find vertical side lengths

The total vertical length on the left - hand side is equal to the sum of the vertical lengths on the right - hand side. The vertical lengths on the right are \(4 + 3=7\) cm.

Step2: Find horizontal side lengths

The total horizontal length on the top is equal to the sum of the horizontal lengths on the bottom. The horizontal lengths on the bottom are \(6 + 2\) cm.

Step3: Calculate perimeter

Perimeter is the sum of all side lengths. The figure can be thought of as a rectangle's perimeter. The lengths of the sides are \(6 + 2\) (horizontal) and \(4+3\) (vertical). The perimeter \(P=(6 + 2+4 + 3)\times2\). First, \(6+2+4 + 3=15\), and \(15\times2 = 26\) cm.

Answer:

26 cm
