Question

A quarter circle of radius 3.5 cm is cut away from each corner of a square of side 7 cm . find the area and perimeter of the remaining figure (shaded).

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

10.5cm squared and 22cm squared

Step-by-step explanation:

First find the perimeter and area of the circle

Perimeter of the circle=2πr
                                   = 2*22/7*3.5
                                  =22cm^2
Area of the circle= πr²
                             =22/7*3.5*3.5
                              =38.5 cm²

Area of square= s*s which is 7*7cm= 49cm

Area of the shaded part= Area of circle-Area of square

                                      =10.5cm²

Hope it helps!
