what is the value of b for the following triangular prism? remember that there are 10 millimeters in a centimeter.
3 cm2
30 cm2
15 cm2
1.5 cm2

For B, do you mean the area of the base of the triangular prism?

If this is the case, then:

Step-by-step explanation:

As you can see, the base of a triangular prism is basically a triangle. So, if you need to find the area of its base you can calculate it using the formula for the triangle area, which is given by:

Before going any further we need to do a conversion in order to work with the same units:

Now, the value of B is given by:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
