Answer
Parallelogram.
$Area=288~mm^2$
$Perimeter=78$ mm
Work Step by Step
The figure is a parallelogram.
We know that the area of a parallelogram is given by:
$Area=base*height$
$A=bh$
So we have:
$A=24*12$
$A=288~mm^2$
To find the perimeter, we simply add up the side lengths:
$Perimeter=24+15+24+15$
$Perimeter=48+30$
$Perimeter=78$ mm
