Answer:
This is an isosceles right triangle, then we have
2 x u^2 = [6sqrt(2)]^2

<=> u^2 = 36
<=> u = 6

Step-by-step explanation:
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
