Question

find the area of shaded region in the following feature
please explain it step by step by solving ​

Answer 1

Answer:

a) 51 $m^{2}$              b) 125 $m^{2}$      

Step-by-step explanation:

A)  Area of square = S x S

    Area of Exterior Box = 10 x 10

                                       = 100 $m^{2}$

    Area of Interior Box = 7 x 7

                                      = 49 $m^{2}$

   Area of Shaded Box = 100 - 49

                                       = 51 $m^{2}$

B) Area of large square = 15 x 15

                                       = 225 $m^{2}$

   Area of Small Square = 5 x 5

                                        = 25 $m^{2}$

   ∴ no of 4 small square = 25 x 4 = 100

    Area of the shaded = 225 - 100

                                      = 125 $m^{2}$
