Question

the length and the breadth of a rectangular field is 100 in the ratio of 3 : 2 the area of the field is​

Answer 1

Answer:

3x,2x=let area be

area =l*b

perimeter =2(l+b)

100=2(3x+2x)

3x+2x=50

5x=50

x=10

l=3x==3*10=30cm

b=2x=2*10=20cm

require area =l*b

30*20=600cm square

Answer 2

$let \: length \: be \: 3x \: and \: \: breadth \: be \: 2x \: \\ perimeter = 100cm \\ p = 2(l + b) \\ 100 = 2(3x + 2x) \\ 100 = 10x \\ x = 10 \\ so \: \: length = 30cm \\ breadth = 20cm \\ area = l \times b \\ = 30 \times 20 \\ = 600cm {}^{2}$
