Question

Find the area of the shaded region. 10 cm 16 cm B. E 8 cm 18 cm F 18 cm 8 cm C D+ 26 cm ​

Answer 1

Answer:

Answer is 78cm²

Step-by-step explanation:

Steps -:

Length of the figure is 26 cm

First Breath of figure = 18 cm

First Triangular breath of the figure = 8 cm

Second breath of the figure = 8 cm

Second Triangular brath of the figure = 18 cm

So, Area of the figure = Sum of all sides ( including all )

= 26+18+8+8+18cm²

= 78 cm² Ans.

Answer 2

Answer:

522cm²

Step-by-step explanation:

Area of ABCD = s×s

=26cm×26cm

=676cm²

area of ∆AFE =1/2×b×h

=1/2×8×16

=64cm²

area of ∆EBG =1/2×b×h

=1/2×10×18

=90cm²

area of shaded region =area of ABCD - (area of ∆

AFE + area of ∆EBG )

= 676-(64+90)

= 676-154 cm²

= 522cm²
