Answer 1

Step-by-step explanation:

Area of rectangle=length×breadth

lets assume,

length (L)=2m

breadth (B)=70cm=70/100=0.7m (cm converted to m)

∴ Area of rectangle =L×B

=2×0.7

=1.4 m square

Step-by-step explanation:

ᴀʀᴇᴀ ᴏғ ʀᴇᴄᴛᴀɴɢʟᴇ= ʟᴇɴɢᴛʜ * ʙʀᴇᴀᴛʜ

ʟᴇᴛ's ᴀssᴜᴍᴇ,

ʟᴇɴɢᴛʜ (ʟ) = 2m

ʙʀᴇᴀᴛʜ (ʙ) =70cm = 70/100 = 0.7 m (cm converted to m)

Area of rectangle = l*b

= 2*0.7.
