Answer:
0.00007935
Step-by-step explanation:
7.935 x 10 to negative 5 power can be written as:
7.935 x 10^(-5)
A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

When dividing by tens, move the decimal to the left by the amount of 0's
So our answer is 0.00007935
Answer:
45 square meters
Step-by-step explanation:
we know that
The area of trapezoid is equal to

where
b1 and b2 are the parallel bases
h is the height of trapezoid (perpendicular distance between the parallel bases)
we have

substitute


When you find area it is bxh for a rectangle so we have (4x3)x2 + 4x(7x3)=108
