Easiest way is to put it on a grid and count squares. Alternatively, you could break the heart down into tiny manageable sized (and manageable shaped) chunks, calculate all the areas then add them together.
You times the length by width, to get the area of the 2D shape.
A=3.14 1/2d time r2
It has no volume because it's a 2D shape but its surface area is:- length*perpendicular height
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
what kind of measurement to use when finding the area of a 2d shape

You can find the aerea of any 2d shape.
A=3.14 1/2d time r2
It has no volume because it's a 2D shape but its surface area is:- length*perpendicular height
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
what kind of measurement to use when finding the area of a 2d shape
The answer is zero. A 2D shape has no volume.
There is none because a trapezoid is a 2D shape but the area is as follows measured in square units:- Area = 0.5*(sum of parallel sides)*height
Formula for area of a circle is A = pr2r = 1/2d = 12.5cm, p = 3.142A = 3.142 x (12.5cm)2A = 490.9375cm2
The units for area is square centimetres, not centimetres.
Area is used to represent the amount of space in a 2D object.
Height, width, area, perimeter.
