Here is the complete question :

A farmer's field has the dimension shown He needs to find the area of the field so that he knows how much seed to buy, and the perimeter so he can buy the fencing. Using the model find the area and perimeter of the field.

area of a rectangle = length x breadth

1 2/5 x 2 1/3

convert the mixed fractions to improper fractions

7/5 x 7/3 = 49/15 = 3 4/15 km²

Perimeter of a rectangle = 2 x (length + breadth)

2 x (1 2/5 + 21/3)

2(
`1(2)/(5) + 2(1)/(3)`)

2(
`3(6 + 5)/(15)`)

2(
`3(11)/(15)`)

2 x 56/15 = 112/15 = 7 7/15 km
