Question

Quadrilaterals and Polygons

Answer 1

Did you try it? @Trexy

Answer 2

Find the side lengths:
1) (0, 3) and (3, 0)
2) (3, 0) and (0, -3)
3) (0, -3) and (-3, 0)
4) (-3, 0) and (0, 3)

Check if they are equal!

Next find the slopes of each sides

Answer 3

@Trexy are you here?

Answer 4

Hey @ash2326 Im back..
So far I got the Slope:
AB=-1
BC=1
CD=-1
AD=1

and next i got the distance formula:
AB=4.24
BC=4.24
CD=4.24
AD=4.24

sORRY FOR THE LATE REPLY..

Answer 5

and its SQUARE
Im guessing perimeter is 16.96?
Im not sure how to do area for this? Please

Answer 6

to do area find the length of 2 sides using the distance formula

Answer 7

like how @timo86m ?

Answer 8

if you know for sure it is a square then just find 2 sides perpendicular and use the distance formula to find the 2 sides.

Answer 9

ok so its 17.9776 right?

Answer 10

@timo86m and @Calcmathlete please?

Answer 11

is that what you drew?

Answer 12

top half lol

Answer 13

here timo

Answer 14

it 18 i think i uploading pic

Answer 15

oh wait that is area lol

Answer 16

18

Answer 17

@Trexy we found all the sides are equal
and AB and BC are perpendicular to each other ( slopes product is -1)
if we check all the adjacent sides are perpendicular to each other
so this is a square

Answer 18

perimeter is sqrt(18)*4=16.970562

Answer 19

Area of square= a^2
Perimeter= 4 \times side length

Answer 20

hw did you get that, cuz my dad is asking, since i got \[4.24\times4.24=17.977\]
or its actually the same ?

Answer 21

\[\sqrt {18}=4.24\]
But it's mot exact , your area will be exact that's 18

Answer 22

*not

Answer 23

since area of square = a^2 and one side is sqrt(18)

then

(sqrt(18))^2=18 :)
