Hi Dejan. Here's another approach. Connecting a pair of opposite corners with a straight line will divide the shape into two triangles. There's an area formula for triangles that works when all three side-lengths are known. If you're unable to measure the diagonal's length at scale, then you could enlarge the image on paper and measure both the added line and the longest given line. A proportion may be used to scale-up the drawn line's measure to meters. The area will be an estimate -- the better you measure, the better the estimate.How do I find the area of this shape by breaking it down into multiple shapes?
Can you assume that the right -bottom corner is 90 deg?How do I find the area of this shape by breaking it down into multiple shapes? Please help I need it to complete an assessment task
In the image the slope of the right edge is about 4% from the vertical, i.e. the angle is about 87.7 degrees.Can you assume that the right -bottom corner is 90 deg?
Yes, I saw that and I was trying to define a possible constraint so that solution is possible.In the image the slope of the right edge is about 4% from the vertical, i.e. the angle is about 87.7 degrees.
I measured dimensions in pixels and found that the scales vary by about 4%, which tells me that there is some perspective distortion in the picture. I wonder what the required precision is for this task.Yes, I saw that and I was trying to define a possible constraint so that solution is possible.
Oops... I've revisited my data, and the differences in scales are at most 1.7%. When I average (geometrically) the scales I get at most 1.1% difference with the average. I'd guess that the distortion in my computation of the area should not be more than 2%.I measured dimensions in pixels and found that the scales vary by about 4%, which tells me that there is some perspective distortion in the picture.
