d. 116 cm

  1. what is the area of the figure?

a. 648 cm²
b. 710 cm²
c. 741 cm²
d. 837 cm²

Explanation:

Step1: Calculate the perimeter of the figure

The perimeter of a shape is the sum of all its sides.
For the given figure, we can calculate the perimeter as follows:

  • The top side is \(31\) cm.
  • The bottom side is \(27\) cm.
  • The two vertical sides on the left and right:
  • The left side has two parts: \(3\) cm and \(24\) cm.
  • The right side also has two parts: \(3\) cm and \(24\) cm.
  • The remaining two sides (the "extensions" on the top):
  • Each extension has a length of \((31 - 27)\div2= 2\) cm.

Step2: Calculate the area of the figure

The figure can be divided into two rectangles.

  • The first rectangle (the top part) has dimensions \(31\) cm (length) and \(3\) cm (width).
  • The second rectangle (the bottom part) has dimensions \(27\) cm (length) and \(24\) cm (width).
$$ LATEXBLOCK1 $$

Answer:

  1. D. \(116\) cm
  2. C. \(741\) cm²
