Answer:
H) 0.75
Step-by-step explanation:
4.5 divided by 6 is 0.75
We don't use remainders in algebra for the most part. We have to do regular division. I'll try to show it here:
____._7___5_____________
6 ) 4 . 5 0
4 . 2
____________
0 . 3 0
0 . 3 0
_____________
0
By pythagorean theorem
a^2+b^2=c^2
We can find that PL is 12.65
and then by altitude theorem
MA*LA=PA^2
we can find the value of MA
12MA=16
MA=1.33
then by the pythagorean theorem
we can use to find PM
MA^2+PA^2=PM^2
so PM=4.22
then to find the are you multiply length by width
PM*PL
12.65*4.22
So the area is 53.38
