Answer:
132 square units
Step-by-step explanation:
We are to find the surface area of a square pyramid.
From the diagram above, we are given:
Slant height = 6 units
Base = 8 units
The formula is given as:
= 2bs + b²
= 2 × 8 × 6 + 6²
= 96 + 36
= 132 square units
2x + y = 4
2x - y = 8
-------------add
4x = 12
x = 12/4
x = 3
2x + y = 4
2(3) + y = 4
6 + y = 4
y = 4 - 6
y = -2
okay....so x = 3 and y = -2
3x - y = ?
3(3) - (-2) = ?
9 + 2 = 11....so ur answer is 11
Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
