answer
formula 2 points
if x = 13 cm, y = 6 cm, and z = 25 cm, what is the area of the figure show below?

Explanation:

Step1: Recall perimeter formula

The perimeter of a figure is the sum of the lengths of all its sides.

Step2: Add side - lengths

Perimeter = AB + BC+CD + DE+EF + FG+GH+HA. Since we can observe that the horizontal lengths on the top (AB) and the sum of the horizontal lengths on the bottom (HG + EF) are equal, and the vertical lengths on the left and right can be paired up in a way that the non - labeled vertical lengths can be accounted for by the given vertical lengths. So, Perimeter=(AB + BC+CD + DE+EF + FG)+(AB + BC+CD + DE+EF + FG)=2×(8 + 4+1 + 2+4 + 1)

Step3: Calculate the sum

2×(8 + 4+1 + 2+4 + 1)=2×20 = 40

Answer:

40
