Question

what is the perimeter of the trapezoid? 10 cm 13 cm 13 cm 20 cm a 26 cm b 30 cm c 46 cm d 56 cm

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a polygon is the sum of the lengths of its sides. For a trapezoid with side - lengths $a$, $b$, $c$, and $d$, $P=a + b + c + d$.

Step2: Identify side - lengths

Here, $a = 10$ cm, $b = 13$ cm, $c = 13$ cm, and $d = 20$ cm.

Step3: Calculate perimeter

$P=10 + 13+13 + 20=56$ cm.

Answer:

D. 56 cm
