Question

The perimeter of a rectangular field is 280 m. If the length of the filed is 80 m, find the area of the field.

Answer 1

Answer:

▪Perimeter = 2(l+b)=280m

2(l+b)=280m

l+b=280/2=140m

▪length =80m(given)

l+b=140m

80m+b=140m

breadth =140-80=60m

▪Area=length ×breadth =80×60=4800sq.m

Answer 2

Answer:

4800 cm²

Step-by-step explanation:

given,

perimeter = 280cm

length = 80cm

so,

perimeter = 2(l+b)

280 = 2(80+b)

280 = 160+2b

280-160 =2b

120/2 =b

60 = b

now,

length = 80cm

breadth = 60cm

so,

area = l*b

= 80*60

=4800 cm²
