Question

17. The perimeter of a rectangular field is 480 m, the ratio between its length and
breadth is 5: 3. What is the area of the field ?
(a) 7200 sq. m (b) 13500 sq. m (c) 15000 sq.m (d) 54000 sq.m​

Answer 1

Answer:

b

Step-by-step explanation:

perimeter = 2(l+b)

ratio given is 5:3,

so  length =5x ;breadth =3x

perimeter = 2 (5x+3x)

480= 2(8x)

240=8x

30=x

then we get length=150 ; breadth = 90

area = 150 multi[plied by 90

        =  13500 sqm
