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.

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.

You can find the aerea of any 2d shape.

The answer is zero. A 2D shape has no volume.
Formula for area of a circle is A = pr2r = 1/2d = 12.5cm, p = 3.142A = 3.142 x (12.5cm)2A = 490.9375cm2
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
Area is used to represent the amount of space in a 2D object.
The units for area is square centimetres, not centimetres.
Height, width, area, perimeter.
