Answer:
9/16 m.
Step-by-step explanation:
When you cut two pieces along its diagonal it causes it to be two congruent triangular pieces.
<em>You need to multiply the length and the width to find an area:
</em>
1 1/2 × 3/4
<em>Now you need to change it into an improper fraction:</em>
1*2+1 = 2+1 = 3; this gives us 3/2:
3/2 × 3/4 = 9/8 = 1 1/8
<em>Dividing it by 2:</em>
9/8 ÷ 2
I believe A and B are the ones. As for explaining? hmm. I would honestly say that any number to the right of a number is a tenth of the place above it. But then again, it's optional to explain ;P
I think the answer would be x= 4/7 y = +-16/7
= 0.2
