Question

Please give answer to this question. ​

Answer 1

Step-by-step explanation:

1) perimeter=300m

2)the sides = 50 cm and 40cm

length=50cm

3)the perimeter=34m

cost of fencing 34m=34×25

= rs.850

Answer 2

Answer:

1)300m

2)L=25 cm

B=20 cm

3)850 rupees

Step-by-step explanation:

1)L=85 m

B=65 m

P=2(L+B)

=2(85+65)

=2(150)

=300 m

2)P=90 m

Let Length=5x and Breadth=4x

90 cm=2(5x+4x)

90 cm =2(9x)

90 cm=18 x

18 x =90 cm

x=90/18

x=5

L=5x=25cm

b=4x=20cm

3)P=2(l+b)

P=2(10+7)

=2(17).

=34 m

Cost of fencing per metre=25 rupees

Cost of fencing 34 m=25×34

=850 rupees

I hope it helps you!
