A rectangular piece is 20 m long and 15 m wide. From its four corners, quadrants of radii 3.5 m have been cut. Find the area of the remaining part.

Question

Philoid · Accepted Answer

Area of the plot = area of the rectangle - 4 × area of one quadrant

Radius of semi-circle = 3.5 m

Area of four quadrants = area of one circle

Area of the plot = length × breadth + πr²

Area of the plot = 20 × 15 -

Area of the plot = 300 – 38.5 = 261.5 m²
