1.) It's a parallelogram
area:
3.5 x 5.8 = 20.3
perimeter:
4 + 4 + 5.8+5.8 = 19.6
2.)It's a right triangle
<span> area:
</span> (6.92 x 11) ÷ 2 = 38.06
<span> perimeter:
</span> 6.92 + 11 + 13 = 30.96
3.) ...that looks like a square tbh xD
<span>area:
</span>4.4 x 3 = 13.2
<span>perimeter:
</span>2.4
4.) Trapezoid
x + y = 6
relationship: x = 6 -y or y = 6-x
so answer: c. y = 6 - x
show work:
x + y = 6
subtract x to both sides
x + y -x = 6 -x
simplify
y = 6-x
X=6 is a line parallel at x=6 to the y-axis
the line perpendicular to line x is parallel to x-axis at y= 7, hence this new line has a function y=7
