What is the surface area of the right prism given below? O A. 298 units2
OB. 840 units2
O C. 480 units2
O D. 420 units2

480 units^2

Step-by-step explanation:

5 * 12 =  60

13 * 14 = 182

12 *14 =  168

5 * 14 =  70

            480

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

were is the equation
