No change in area if sides of rectangle are equal.
Hope this helps.
9/11 is the answer because 1 and 1/2 x 6 is 9
Since decimals have places in 10 100 and 1000 you need a denominator with those number but since you already have a 10 you take the 7 and add a 0. in front so the answer is 0.7
I got 7.1 x 10^(-11) but it's been a few years so I could've done it wrong
