Question

find the area and perimeter of a rectangular field whose length and breadth are 42 1/5 m and 34 3/4 respectively​

Answer 1

Step-by-step explanation:

length = 42 1/5 = 5×42+1/5= 211/5m

breadth = 32 3/4= 4×32+3/4= 131/4m

area of rectangle = Length x breath

= 211/5×131/4= 27641/20

= 1382.05 m²

perimeter of rectangle = 2(length + breadth)

= 2( 211/5+131/4)

= 2(844+655/20)

= 2(1499/20)

=2(74.95)
