Start here:  A = 18 ft^2 = L * W.  Next, L = 2W.

Merging these 2 formulas lets us eliminate L:

18 ft^2 = (2W) * (W) = 2W^2.

So W^2 = 9 ft^2, and W=3 ft.  Please use L = 2W (from above) to calculate L.

A vertical plane passes through a pyramid that has a horizontal base.
Kay [80]

A triangle will be produced from the intersection of the vertical plane and pyramid. The correct options are triangles and trapezoid.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.

Given that a vertical plane passes through a pyramid that has a horizontal base. Therefore, when the vertical plane and the pyramid meets or intersect the two dimensional figure that will be produced when the two intersect is triangle. It can also be trapezoid if the vertical plane does not intersect exactly in mid of the pyramid.

Hence, a triangle or a trapezoid will be produced from the intersection of the vertical plane and pyramid.

Im confused that's all - If 80% is 75 marks, what is full marks
never [62]

Let the full marks be represented by = x

As given, 80% of x is 75

So,

\frac{80}{100}*x=75

x= 80x=7500

x=93.75

Hence, full marks is 93.75

We can check also- \frac{80}{100}*93.75 =75
