Question

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

Answer 1

HEY.......
HERE IS U R ANSWER
=============================
AREA OF QUADRANT = πr^2=
$\frac{22}{7} \times 3.5 \times 3.5$
= 11 * 3.5
= 38.5 m^2

AREA OF CIRLCE = 4 * 38.5 = 154 m^2

AREA OF PIECE = 20 *15 = 300

REMAINING AREA = 300 - 154
= 146 m^2
