What is the value of b for the following triangular prism?

5.25 cm2
56 cm2
52.5 cm2
5.6 cm2

A.

Step-by-step explanation:

We have been given an triangular prism. We are asked to find the value of B for our given prism.

, where,

B = Area of base,

h = Height of prism.

The value of B for our given prism would be the area of base. Upon looking at our given prism, we can see that base of our given prism is triangular, so we will use area of triangle to find the value of B.

1 mm = 0.1 cm

28 mm = 2.8 cm

Therefore, the value of B is 5.25 square centimeters and option A is the correct choice.  

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
