Meters are 100 times as large as centimeters. So, if we have 800 centimeters, that is the equivalent of 8 meters.
In this scenario, we want to know how many meters is equivalent to 7
centimeters. Since 1 centimeter is 1/100 of 1 meter, we can multiply the
amount of centimeters by 1/100 to get the measurement in meters.
7(1/100) will yield 7/100 or .07 meters.
To write this in scientific notation, we take 7 and multiply it by 1/100 or 10^(-2). This is written "7x10^(-2) m".
7 centimeters in scientific notation is just 7x10^0 because it is a
single unit. Scientific notation allows us to compare the size of
numbers more easily.
For instance 7.12x10^3 is much larger
than 7.12x10^(-3) due to the exponents and how many "10s" we are
mulitplying our number by.

Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²
