Answer:
145 yards squared
Step-by-step explanation:
So the area of the base is area of a square with side length of 5 yards 
The area of one triangular face base times height divided by two and then simply multiplied by 4 because there are 4 triangular faces.

So the total surface area is
yards squared
You either find the gradient or distance and if there are equal, therefore the opp are equal
2-5 x 1/2 = 0.2 (Length x Width)
