The total surface area of the given pyramid is:
A = 39ft²
<h3>
How to get the surface area of the given figure?</h3>
The total surface area will be equal to the sum of the areas of the square and the 4 triangles.
Remember that for a square of side length S, the area is:
A = S².
In this case, S = 3ft, then:
A = (3ft)² = 9ft².
Now, the area of a triangle of base B and height H is:
A = B*H/2.
Here we can see that the triangles have a base of 3ft (the sides of the square) and a height of 5ft, then the area of each triangle is:
A = (3ft)*(5ft)/2 = 7.5 ft²
Then the total area of the figure is:
A = 4*(7.5 ft²) + 9ft² = 39ft²

By looking at ur answer choices, I am assuming the width is 2/5 inches and the length is 3/5 inches.
A = L * W
A = 3/5 * 2/5
A = 6/25 in^2 <==

Answer:
base = 2 m; height = 6 m
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- base of 8 meters
- height of 6 meters
- top side length of 4 meters.
=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters
=> the base of the triangles:
= (the base of the trapezoid - the top side length) / 2
= (8-4)/2
= 2
So the base and height of one of the triangles : base = 2 m; height = 6 m
Hope it will find you well.
