(A )Given length=13.5 m, Breadth=10.5 m
Every rectangle has two equal right triangles.
Area of each right triangle $=\frac{1}{2}×13.5×10.5=70.875{m}^{2}$
(B) Given length=18 m , Breadth=8 m
Every rectangle has two equal right triangles.
Area of each right triangle $=\frac{1}{2}×18×8=72{m}^{2}$
(C) Given length=1.5 m , Breadth$=30cm=\frac{30}{100}=0.3m$
Every rectangle has two equal right triangles.
Area of each right triangle $=\frac{1}{2}×1.5×0.3=0.225{m}^{2}$
