What you do is you multiply the base by the height then you must half your answer. Eg: A triangle with a base of 2 cm and a height of 4cm, you would do 2x4=8 then half your answer to get 4cm squared.

The area of any triangle is (1/2) x (length of the base) x (height). We're sure you can take it from there.

1/2*4*3 = 6 square cm

A=1/2(b)(h). So A=1/2(6cm)(4cm). A=12cm^2, or 12 squared centimeters.

Based on your wording, 4 cm could be the slanted height or the vertical height..._______./............./4cm/______ /or..._______./|...........| // |__4cm.|/However, since the top rhombus's area cannot be solved with this information (you need the angle of slant), I will assume that your problem refers to the bottom picture (the vertical straight lines are the height).You might notice that the triangle on the right and the triangle on the left appear to be the same, and you would be right. If you actually move the triangle, you get a 4cm x 4cm square, and we can now calculate the area.A = ss (area of a square)A = (4cm)2 = 16cm2Therefore, the rhombus has an area of 16 square centimeters, or cm2.
