Answer

1. P=2(l+w)

=2(30m+20m)

=2(50m)

=100m

A=lw

=(30m)(20m)

=600m²

2. P=4s

=4(15m)

=60m

A=s²

=(15m)²

=225m²

3. P=2(l+w)

=2(100cm+50cm)

=2(150cm)

=300cm

A=lw

=(100cm)(50cm)

=5000cm²

4. P=4s

=4(20m)

=80m

A=s²

=(20m)²

=400m²

5. P=2(l+w)

=2(40m+30m)

=2(70m)

=140m

A=lw

=(40m)(30m)

=1200m²
