1. Draw an accurate picture of the triangle in
the coordinate axes, as shown in the attached picture.
2. Circumscribe a rectangle about the triangle, as shown in
the picture. The coordinates of the points M, N, T are easily identifiable as shown in the
picture.
3. The area of the triangle ABC is The area of
the rectangle - Area 1- Area 2- Area 3.
Area 1 = 1/2(3*7)=21/2
Area 2 = 1/2(4*4)=1/2*16=8
Area 3 = 1/2( 3*7)=21/2
Area 1+Area 2+Area 3=21/2+21/2+8=21+8=29 (units squared)
Area rectangle= 7*7=49 (units squared)
Answer: Area of triangle is 20 units squared.
