Hello,

Please, see the attached files.

The area of shaded region is the difference between the area of a square and the area of a triangle:

Square. Side: s=18 in

Area of the square: A1=s^2→A1=(18 in)^2→A1=324 in^2)

Triangle. Base: b=18 in; Height: h=9 in

Area of the triangle: A2=1/2 b∙h→A2=1/2 (18 in)∙(9 in)→A2=1/2 (162 in^2 )→A2=81 in^2

The shaded area “A” is the difference of the area of the square and the area of the triangle:

A=A1-A2→A=324 in^2 - 81 in^2→A=243 in^2

The area of the shaded region is 243 in^2     7-N

The area of shaded region is the difference between the area of a rectangle and the area of a triangle:

Rectangle. Base: b=17 cm; Height: h=11 cm

Area of the rectangle: A1=b∙h→A1=(17 cm)∙(11 cm)→A1=187 cm^2

Triangle. Base: b=17 cm; Height: h=11 cm

Area of the triangle: A2=1/2 b∙h→A2=1/2 (17 cm)∙(11 cm)→

A2=1/2 (187 cm^2)→A2=93.5 cm^2

The shaded area “A” is the difference of the area of the rectangle and the area of the triangle:

A=A1-A2→A=187 cm^2 - 93.5 cm^2→A=93.5 cm^2

The area of the shaded region is 93.5 cm^2    The figure is cut and we can' t read the value.

Thanks.
