Why is the Area of triangle 4 × 3? Shouldnt it be 1/2 × 4 × 3?
My apologies, forgot to multiply by 1/2, yes, you are correct, it's 1/2 x 4 x 3 for the area of 1 triangle
Area of 1 triangle = 0.5 cmx 4cm x 3cm = 6cm square
Number of triangles that can be cut = 1260 divide by 6 = 210
Area of 1 triangle = 0.5 cmx 4cm x 3cm = 6cm square
Number of triangles that can be cut = 1260 divide by 6 = 210
Thanks
Sure thing
