The following are the dimensions of a few rectangles. Find the are of the two right triangles that are cut from the rectangles using the formmula of the area of a triangle. A. Lenght= 13.5 m, Breadth=10.5 m B. Lenght=18 m, Breadth=8 cm C. Lenght=1.5 m, Breadth=30 cm

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