<u>Answer:</u>

The correct answer option is b. Perimeter = 19.2 units, Area = 22 units^2.

<u>Step-by-step explanation:</u>

We are given a pentagon ABDEC and we are to find its perimeter.

From the given figure, we can clearly see that the pentagon can be divided into two shapes, a square and a triangle. One side of each of these shapes will be excluded from the perimeter.

Distance of AB = \sqrt{(4-1)^2+(6-4)^2} = \sqrt{13} =3.6

The length of AB and AC are same and the BD, DE and CE are same (4 units).

Perimeter of pentagon ABDEC = 4 + 4 + 4 + 3.6 + 3.6 = 19.2 units

Area = (area of ΔABC) + (area of square BDEC)

= (\frac{1}{2} *4*3)+(4*4)

= 22 units^2

Pyramid A is a square pyramid with a base side length of 7 inches and a height of 6 inches. Pyramid B has a volume of 3,136 in?.
anygoal [31]

Answer:

WE HAVE FIND HOW MUCH MAY TIME BIGGER IS THE VOLUME OF PYRAMID B THAN PYRAMID A.

The answer is 32 times

Step-by-step explanation:

Volume of Pyramid B = 3136 in³

Volume of Pyramid A = ?

We have to find volume of Pyramid A. As Pyramid is a square pyramid, its volume is given as:

V=\frac{(b^2)(h)}{3}

where b = base = 7  and h = height = 6. Substitute the values:

V=\frac{7^2\cdot6}{3}\\V=98\\

Volume of Pyramid A = 98 in³

To find how many time B is bigger than A, divide volume of B by A:

\frac{3136}{98}=32

So, volume of Pyramid B is 32 times bigger than volume of Pyramid A
