Question

Please Find the area of the shaded region​

Answer 1

Answer:

Step-by-step explanation:

Area of shaded region = Area of bigger rectangle - Area of Smaller rectangle

Area of bigger rectangle= l × b

                                         = (4x+3) (4x-3)  = (4x)²-(3)²= (16x²-9) sq. units

Area of smaller rectangle= l × b

                                         = (8x+9)(2x-1) = 8x(2x-1) +9(2x-1)

                                         = 16x² -8x +18x - 9 = (16x²+10x-9)sq. units

Area of shaded region= (16x²-9) - (16x²+10x-9)= 16x²-9-16x²-10x +9

                                    = -10x sq. units

                                    = 10x sq. units
