(1) One side of E is 10 and one side of R is 8.
(2) 8 is the smaller side of R

Let's see what each statement tells us..
1) One side of E is 10and one side of R is 8.

So area of E =$$10^2*\frac{√3}{4}=25*√3=25*1.732~42$$
Now 8 can be equal side of R or the hypotenuse, but larger area will be when EQUAL sides are 8.... Area=1/2 *8*8=32..

So in all cases ans is YES
Suff

2) 8 is the smaller side of R..
Nothing much
Insufficient
