Question

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

Answer 1

Answer:

Step-by-step explanation:

GIVEN

BASE OF PARALLELOGRAM = 60 CM

HEIGHT OF PARALLELOGRAM = 30CM

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

AREAOFPARK=(base)×(height)

=(60)×(30)

=1800cm

RADIUS OF CIRCULAR POND = 7 CM

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

AREAOFPOND=πr

NOW AREA OF REMAINING PART

\begin{gathered}AREA \: \: OF \: \: REMAINING \: \: PART \\ =1800 - 154 \\ = 1646\end{gathered}

AREAOFREMAININGPART

=1800−154

=1646
