Question

i will mark u as brainlist plz help me
∆ABC is right angled at B. AB=15cm, BC=20 cm with vertices A, B and C as centres area are drawn each of radius 7cm. find the area of the shaded region.​

Answer 1

Answer:

AB=15cm

BC=20cm

AC=$\sqrt{x} 20square+15square$

  or, =$\sqrt{x} 400-225$

 or, =$\sqrt{x} 625$

   or, =25

Area of triangle=1/2*base*height

                              = 1/2*20*15

                              =150

Area of shaded region=$\pi$rsquare

                                    =22/7*7square

                                        =22*7

                                          =154
