Question

the same size. 27 cm 14 cm what is the perimeter of the figure? cm

Explanation:

Step1: Find the length of the large - rectangle

The length of the large rectangle is composed of 3 equal - length segments of 14 cm each. So the length $l = 14\times3=42$ cm.

Step2: Recall the perimeter formula

The perimeter formula for a rectangle is $P = 2(l + w)$, where $l$ is the length and $w$ is the width. Here, $l = 42$ cm and $w = 27$ cm.

Step3: Calculate the perimeter

$P=2\times(42 + 27)=2\times69 = 138$ cm.

Answer:

138
