Answer:
C. 30.66 square meters
Explanation:
The equation for area is A = L × W
L = length
W = width
Because a demimeter is 1 tenth of a meter your new measurements are 7.3 and 4.2.
multiply the measurements to find the area of 30.66² meters
C
change decimetres into metres
length - 7.3m
Width - 4.2m
to find an area, do length times width
7.3 x 4.2 = 30.66 square metres
I hope this helped :)
