I have to figure out how many square meters there are inside this... first wall, 67.76 meters long, next, 49 meters, then 63 meters and finally, the last wall is 24.03 meters long. Does anyone know the correct formula to use so I can figure this out? Thank you.

You need to know the height to figue your square meters.

If this is for a floor and these are the surrounding walls then you square them up to make them common. After that with the remainder you should have a triangle and you use that to figure the rest.

You only need the height for cubic meters. Square meter figures are derived the same as squre yards.

I'm just really bad at math. How would you solve this? What math formula would you use? I really want to know for future refferences. Thanks

Maybe I was misreading the question. I took it to mean the numbers posted were the wall lengths. I didn't see any mention of height. What is the OP trying to solve ?

Divide the area up into rectangles and triangles.

Compute the area of each.

Area of rectangle is side a X side b.
Area of triangle is base X height divided by 2.

There is no height. I just need to figure out how big the property is.

Height is height of triangle.

CDO3 you were right in your area determination. You do need the height of a triangle to get the area. But for area it is planar height not altitude height. I believe he is looking for area, not volume. Georgia dad of 4 (MA0641)
