Solution

STEP 1 : Finding the perimeter of rectangle
Length of rectangle $(l) = 2.3 m = 2.3 \times 100 c m = 230 c m$
Breadth of rectangle $(b) = 85 c m$
Perimeter of rectangle $= 2 \times (l + b)$
Perimeter of rectangle $= 2 \times (230 + 85)$
Perimeter of rectangle $= 2 \times 315 = 630 c m$
STEP 2 : Finding the area of rectangle
Area of rectangle $= l e n g t h \times b r e a d t h$
Area of rectangle $= 230 \times 85 = 19, 550 c m^{2}$
Hence, the perimeter of rectangle is $630 c m$ and area is $19, 550 c m^{2}$ .
