Perimeter = 24
triangle perimeter = 2W + 2L
24= 2W + 2L
12 = W + L
L= 12-W
AREA = W*L
AREA = (W)(12-W)
A = 12W-W^2
maximum occurs when you take the derivative
d/dw=12-2w = 0
w=6
after this i think we can say 6 * 6 = 36 is the maximum area.. not to sure, havent done a problem like this in a while
hope this helps
or if we know what w=6 we can find L
L = 12-w which we still get 6<span />
The area of a 2D form is the amount of space within its perimeter. The total surface area of the square pyramid is 40 meters².
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Henri built a lantern in the shape of a square pyramid. He wants to cover the entire pyramid with fabric. Therefore, the amount of fabric that Henri will need is equal to the total surface area of the square pyramid.
Total surface area = Area of the base + 4(Area of the triangle)
= (4m × 4m) + 4(0.5×4m×3m)
= 16 meters² + 24 meters²
= 40 meters²
Hence, the total surface area of the square pyramid is 40 meters².

Answer:
The ordered pair (-6, -1) is the only solution.
Step-by-step explanation:
-6x + y = 35
Let's plug in the points.
(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35
(-6, -1) --> -6(-6) -1 = 35
(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35
(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35
