Formula to find the area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
For triangles A, B and D, the base occupies 4 squares and the height occupies 4 squares.
Therefore, area = [tex]\frac{1}{2}[/tex] × 4 × 4
= 2 × 4 = 8 sq. units
For triangle E, base occupies 2 squares and height occupies 8 squares.
Therefore, area = [tex]\frac{1}{2}[/tex] × 2 × 8
= 8 sq. units
For triangle C, base occupies 3 squares and height occupies 5 squares.
Therefore, area = [tex]\frac{1}{2}[/tex] × 3 × 5
= 7.5 sq. units
Hence, triangles whose area is 8 sq. units are A, B, D and E.
