Answer:
Given,
Side of square = 100cm
Radius of quadrant, r = 14cm
Angle measure, tita = 90° (angle of each corner of square is 90°)
Step-by-step explanation:
Area of square = (side)²
=(100)²
=10000 cm²
Area of each quadrant = 1/4 * pie * r²
= 1/4 * 22/7 * 14 *14
= 154cm²
Area of remaining part of square = Area of square - 4 * Area of each quadrant
= 10000 - 4 * 154
= 10000 - 616
= 9384 cm²
