Verified Answer :

The sides of a right triangle are
\(a=8-5=3 \\ b=6-4=2 \\ \\A=A_{rectangle}-A_{triangle}=8\times 6- \frac{ab}{2} =48-\frac{3\times2}{2}=48-3=45\)

Answer:

The area of shaded region is 45 square units.

Step-by-step explanation:

The length of the rectangle is 8 and the breadth is 6.

Area of rectangle is

\(A_R=l\times b\)

\(A_R=8\times 6=48\)

The area of rectangle is 48 square units.

Since the opposite sides of a rectangle are equal, therefore the legs of the right angled triangle are

\(l_1=8-5=3\)

\(l_2=6-4=2\)

The area of right angled triangle is

\(A_T=\frac{1}{2}\times l_1\times l_2\)

\(A_T=\frac{1}{2}\times 3\times 2=3\)

The area of triangle is 3 square units.

The area of shaded region is

\(A=A_R-A_L=48-3=45\)

Therefore the area of shaded region is 45 square units.
