find the Perimeter of a rectangle whose length and breadth are 8cm, 70mm
answer
Length = 8 cm which get converted into
80 mm (a cm = 10 mm).
Breadth = 70 mm.
Therefore,
Perimeter = 2×(L+B)
= 2×(80+70)mm =
= 2×(150)mm
= 300 mm =
Therefore,
The answer in cm will be - 300/10
= 30 cm.
Hope this helps you.

Answer:
The perimeter of the rectangle is 17.4cm.
Step-by-step explanation:
length - 8cm
breadth - ( 70mm = 7cm )
perimeter - ( ( 7×2 ) + ( 8×2 ) )cm = ( 14 + 16 )cm = 30cm
