Ответ:
The total area = 850 sq ft
The sub area of the square = 100 sq ft and the trapezoid = 750 sq ft.
Step-by-step explanation:
Given:
The diagram consist of two figure, a trapezoid ( green border)
To find:
The total area.
Formula
The area of square = side × side sq unit
The area of trapezoid = sum of the parallel sides × height
Now,
The area of square = 10 × 10 sq unit = 100 sq ft
The area of trapezoid = (10 + 20) × 25 sq unit
= 750 sq ft
So, the total area can be given as = 100 + 750 sq ft
= 850 sq ft
