Each side of an equilateral triangle = perimeter / 3.
Each side = 10 inches.
The altitude divides the triangle into two 30 60 90 triangles. The hypotenuse is 10 inches and the short side is 5 inches.
altitude^2 = 10^2 - 5^2
altitude^2 = 100 - 25
altitude^2 = 75
altitude =

The area of a trapezoid is as follows:
A =

A and B are the lengths of the parallel lines of trapezoids. The parallel lines in this problem are 3.5 and 9.2. After adding those and dividing by 2, we multiply 17 to find the area of the trapezoid. (This is also shown in the attached picture)
Answer:
the total area of the given figure.
Step-by-step explanation:
Length of the bigger rectangle = 13 ft
Breadth of the bigger rectangle = x
Area of the bigger rectangle = A = 13 ft × x
Length of the smaller rectangle = 5ft
Breadth of the smaller rectangle = y = 6 ft
Area of the smaller rectangle = a = 5ft × 6ft
from the figure :
x + y = 14
x = 14ft - 6 ft = 8 ft
Total area of the figure = A + a

the total area of the given figure.
