Answer:
Area of whole square= 10×10 =100 cm²
Area of 1/4th part of square =5×5=25 cm²
Area of sector= 90°/360°×πr² =1/4×22/7×25=5.5×25/7=137.5/7=19.8 cm ² Aprrox
Area cutted out from the 1/4th part= Area of smaller square- Area of sector= 25-19.8= 5.2 cm²
Area of whole figure= Area of bigger square- Area of cut out
=100-5.2= 94.8 cm²
