Answer:
Area of wall =
ft
Explanation:
First, we know that:
1 in = 1/12 ft
Therefore, the dimensions of the wall would be as follows:
H = 7 ft 10 in =
ft
B1 = 10 ft 2 in =
ft
B2 = 14 ft 1 in =
ft
For the trapezium, area can be calculated using the following the following formula:
Area of trapezium = Average base * height =
* height
Substitute with the given to get the area as follows:
Area of wall = ([ + ] / 2) * 
Area of wall = ft
Hope this helps :)
