Answer:
122.5
Step-by-step explanation:
Use the area formula for a trapezoid (attached below as an image):
A = area in sq cm
a = top base
b = bottom base
h = height
Correspond the correct values with the variables:
a = 14
b = 21
h = 7
A = 1/2 * (14 + 21) * 7
A = 1/2*(35)*7
A = 17.5 * 7
A = 122.5 sq cm

Answer:
You take 6% of a number and the resulting number is 27.
To do this you need to change the percent into a fraction.
6% = 6/100
This is the number you need to multiply to the number you need to find, A.
6/100 A = 27
Solve for x
6 A = 27x100
A= 2700/6
A = 450
Check your answer:
6/100 (A) = 27
6/100 (450) = 27
(6x450) /100 = 27
2700 / 100 = 27
27 = 27

Answer:
20*6 - 120
20*6 = 120
19 * 6 = 114
Step-by-step explanation:
Call x the scale factor.
20x + 19x + 20x = 354 Add the left side together.
59x = 354 Divide by 59
59x/59 = 354/59 Combine and cancel
x = 6
The lengths of the sides are
20 * 6 = 120
19 * 6 = 114
20 * 6 = <u>120</u>
Total 354 Check
