<h2>The area of the total figure is around 535.43 square centimeters.</h2>Step-by-step explanation:
In the image attached, you can notice that all rectangles have a base of 20 centimeters.
Also, each side of the equilaterals triangles is 8 centimeters.
Notice that the height of each rectangle is equal to a side of a triangle.
Using all given vales, the area of each rectangle is
The area of all rectangles is
, because there are three rectangles in total.
The area of each triangle is
The area of both triangles is
Now, the area of the whole figure is the sum of the area of triangles and rectangles
Therefore, the area of the total figure is around 535.43 square centimeters.

Step-by-step explanation:
To solve for q, we apply the leg rule theorem or leg geometric mean theorem :
The hypotenus = 18 + 4 = 22
Leg 1 = b
Part1 = 4
According to the leg rule theorem :
Hypotenus / leg 1 = leg 1 / part 1
22 / b = b / 4
Cross multiply :
b * b = 22 * 4
b² = 88
b = √88 = √88 = √4 * √22 = 2√22
From Pythagoras :
a² = b² - 4²
a² = (√88)² - 16
a² = 88 - 16
a² = 72
a = √72 = √36 * √2 = 6√2
