Answer 1

1. 
s = 2(lw) + 2(lh) + 2(wh)
s = 2(2cmx3cm) + 2(2cmx4cm) + 2(3cmx4cm)
s = (2 x 6cm) + (2 x 8cm) + (2 x 12cm)
s = 12cm + 16cm + 24cm
s = 28cm + 24cm
s = 52cm^2
answer= 3rd option

2.
s = 2(lw) + 2(lh) + 2(wh)
s = 2(1mx10m) + 2(1mx5m) + 2(10mx5m)
s = (2 x 10m) + (2 x 5m) + (2 x 50m)
s = 20m + 10m + 100m
s = 30m + 100m
s = 130m^2
answer= 4th option

3.
s = 2(bh/2) + hw + sw + bw
s = 2(3ftx2ft/2) + (2ftx5ft) + (4ftx5ft) + (3ftx5ft)
s = 2(6ft/2) + 10ft + 20ft + 15ft
s = 2 x 3ft + 10ft + 35ft
s = 6ft + 45ft
s = 51ft^2
answer= 2nd option

4.
s = 6a^2
s = 6 x 2mm^2
s = 6 x 4mm
s = 24mm^2
answer= 3rd option

5.
s = 6a^2
6cm^2 = 6a^26−6a^2=6a^2−6a^2−6a^2+6=0−6a^2+6−6=0−6−6a^2=−6−6a^2/−6=−6/−6a^2=1a=√1a=1 
answer= 1st option

Answer 2

I calculated all of these and got the same answer as Emalthuro - you should be safe
