Answer:
Total Surface Area of the given regular pyramid = 153 units²
Step-by-step explanation:
Base length of the regular pyramid, l = 9 units
Base width of the regular pyramid, w = 9 units
Height of the regular pyramid, h = 7 units
Perimeter of base = 3 × 9
= 27 units
Hence, Total Surface Area of the given regular pyramid = 153 units²
It could round to nearest 100 because the seven tells the four to go up one which makes it fifty which is close to one-hundered
Answer:
area = 26 cm²
Step-by-step explanation:
The formula for the area of a triangle is: area =
Where b = the length of the base and h = height.
In the given problem h = 4 cm and b = 13 cm, so we can plug these values into the equation and multiply:
area = .
4 ? n-3=7 ? Because , unless you work out what 'n' is, you don't know yet what 'n' stands for?
