Answer 1

The perimeter of the composite figure shown in the figure is equal to 5 · [2 + √2 · (1 + √5)] units (approx. 32.882 units) and the total area is 33.5 square units.

How to determine the perimeter and the area of a composite figure

In this case we have a composite figure formed by six triangles and two rectangles. The perimeter is the sum of the side lengths and the area is the sum of the areas of the triangles and rectangles. The perimeter of the entire figure is described below:

p = AB + BC + CD + DE + EF + FG + GA

p = 5√2 + √10 + √10 + 5 + √10 + 5 + 2√10

p = 10 + 5√2 + 5√10

p = 10 + 5 · (√2 + √10)

p = 10 + 5√2 · (1 + √5)

p = 5 · [2 + √2 · (1 + √5)]

And the area of the composite figure is determined by the following expression:

A = 0.5 · (3) · (1) + (3) · (4) + 0.5 · (3) · (1) + 0.5 · (3) · (1) + 0.5 · (3) · (1) + (3) · (2) + 0.5 · (7) · (1) + 0.5 · (6) · (2)

A = 2 · (3) · (1) + (3) · (4) + (3) · (2) + 0.5 · (7) · (1) + 0.5 · (6) · (2)

A = 33.5

The perimeter of the composite figure shown in the figure is equal to 5 · [2 + √2 · (1 + √5)] units (approx. 32.882 units) and the total area is 33.5 square units.
