The areas of the square pyramid are the amount of space on it
- The lateral surface area is 307.2 square cm
- The total surface area is 451.2 square cm
<h3>How to determine the lateral surface area?</h3>
The given parameters are:
Base (b) = 12 cm
Slant height (l) = 12.8 cm
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * 12 * 12.8
Evaluate the product
L = 307.2
<h3>How to determine the total surface area?</h3>
This is calculated using:
T = L + b^2
So, we have:
T = 307.2 + 12^2
Evaluate
T = 451.2
Hence, the total surface area is 451.2 square cm

Answer:
Step-by-step explanation:
Since the triangles are equivalent,
3x - 2 = 5
Solve for x.
3x = 7
x = 7/3
Answer:
100%
Step-by-step explanation:
Perimeter of first garden is given by 2(l+w) where l is length and w is width
Perimeter=2(5+3)=16
The dimensions of second rectangle is doubled hence 10 ft by 6 ft
Perimeter=2(10+6)=32
Change in area will be 32-16=16
Percentage change in area is 16/16*100=100%
