Answer:

Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.

A contractor is building a fenced-in area at a daycare. The area will be rectangular with the length of its base equal to half t
AlladinOne [14]

Answer:

The length of fencing will be 300\ ft

Step-by-step explanation:

Step 1

Find the dimensions of the rectangle

we know that

The area of a rectangle is equal to

A=bh

In this problem we have

A=5,000\ ft^{2}

so

5,000=bh -----> equation A

b=\frac{h}{2} -----> equation B

Substitute equation B in equation A

5,000=(\frac{h}{2})h

10,000=h^{2}

square root both sides

h=100\ ft

Find the value of b

b=\frac{h}{2} -----> b=\frac{100}{2}=50\ ft

step 2

Find the length of fencing

The perimeter of a rectangle is equal to

P=2(b+h)

we have

h=100\ ft

b=50\ ft

substitute

P=2(50+100)=300\ ft
