Step-by-step explanation:

1.) ans is 68 inches squared

the working is : l×w×2=6×1×2=12

l×h×2=6×4×2=48]-add =68 inches squared. w×h×2=1×4×2=8

3). ans is 220 millimeters squared

the working is: l×w×2=10×4×2=80

l×h×2=10×5×2=100]-add = 220 millimeters squared.

w×h×2=4×5×2=40

5). ans is 37ft squared

working: l×w×2=7×2×2=28

l×h×2=7×2×1/2=7]add=37ft squared

w ×h×2=2×1/2×2=2

7). ans is 48 metres squared

working: l×w×2=2×2×2=8

l×h×2=2×5×2=20 add them =48 metres squared.

w×h×2=2×5×2=20

mean, 40.6
