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
