Question

1.
The length and the breadth of a rectangular piece of land are 80 m and 30 m respectively. Find (a)
its area (b) the perimeter (c) the cost of the land if 1 m of the land costs 2 20,000 (d) the cost of
fencing the land with barbed wire @ 45 per m.​

Answer 1

Step-by-step explanation:

a- area of rectangle=lxb

area of rectangle=80*30

area of rectangle=2400m

b- perimeter of rectangle=2*(l+b)

perimeter of rectangle=2*(80+30)

perimeter of rectangle=2*110

perimeter of rectangle=220m

c- cost of 1m land=220000

cost of 2400m land= 2400*220000=528000000rs

d- cost of fencing 1m land=45

cost of fencing 220m land=45*220=9990rs
