Answer: 14.73
Step-by-step explanation:
The given triangle is a right angle triangle.
EF^2 + DF^2 = ED^2
The hypotenuse is |ED| while the two shorter legs are |EF| and |DF|.
We can then apply the Pythagoras Theorem to find the length of EF.
(EF)^2 + (DF)^2 = (ED)^2
(EF)^2 + (12)^2 = (19)^2
(EF)^2 + 144 = 361
(EF)^2 = 361 - 144
(EF)^2 = 217
EF = 14.73
sides 2 * 6 * 4 =48 and 6*4=24
bottom 6*2.5 =15
2.5*4=10
10*2=20 that's the area of 2 smaller sides
Step-by-step explanation:
we add up the dimensions together 48+20+15=83
so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83
