Question

Find the perimetre and area of a plot whose length and breadth are 7 m 50 cm and 4 m 40 cm respectively.

Answer 1

the perimeter and area of the plot whose length and breadth are 7m = 700cm 50 cm

perimeter = 2(700+ 50)

2 × 750= 1500cm

and area = 700× 50 = 35000cm2

the plot whose length and breadth are 4m = 400cm and 40cm

perimeter = 2(400 + 40)

= 2× 440 = 880 cm

and area = 400 ×40 = 1600cm2

Answer 2

$perimetre \: of \: rectangl \\ e = 2 + (l \times b \\ 2 \times (750 + 440 ) \\ 2 \times 1190 = 2380$
