answer all these question plz

Answer 1

Answer:

Step-by-step explanation:

length=l

breadth=b

1)Formula =2(l+b)

=2(800+350)

=2(1050)

=2100m

2) A regular pentagon has 5 sides

so, 20*5

=side*no.of sides

=100cm

3)Perimeter=2(45.5+30.5)

=152m

Cost per metre= Rs.10

Cost for 152 m= 10*152=Rs.1520

4)side =450m

perimeter= 450*4=1800m

Cost per metre= Rs.100

Cost for 1800m=100*1800=Rs.1,80,000

5)a) an equilateral triangle has 3 sides

so, 72*3= 216cm

b) a hexagon has 6 sides

so, 72*6= 432cm

6)Meena

Perimeter of the square park=110*4=440m

Times meena ran around the park=3 times

Total metres meena ran=440*3=1320m

Jaya

Perimeter of the rectangular park=300m

Times jaya ran around the park= 2 times

Total metres jaya ran= 300*2=600m

Thus meena ran more by 720m
