Question

)A park is in the shape of a parallelogram with base 60m and corresponding height 30 cm. If a circular pond of radius 7 cm is constructed inside the park, find the area of the remaining part of the park.

Answer 1

Step-by-step explanation:

• GIVEN

BASE OF PARALLELOGRAM = 60 CM

HEIGHT OF PARALLELOGRAM = 30CM

$AREA \: \: OF \: \: PARK = (base) \times (height) \\ = (60) \times (30) \\ = 1800 \: \: {cm}^{2}$

RADIUS OF CIRCULAR POND = 7 CM

$AREA \: \: OF \: \: POND = \pi \: {r}^{2} \\ \\ = \pi( {7}^{2} ) \\ \\ = \frac{22}{7} \times 7 \times 7 \\ \\ = 154 \: \: {cm}^{2}$

NOW AREA OF REMAINING PART

$AREA \: \: OF \: \: REMAINING \: \: PART \\ =1800 - 154 \\ = 1646$
