Area of the trapezoid=
1/2(b1+b2)×2
A=1/2(8+11)×12
A=1/2(19)×12
A=6×19
A=114 square meters. As a result, the area of the courtyard is 114 square meters. Hope it help!
Answer:
A) Gilligan can conclude that triangle ABC and triangle SDC are similar.
B) He can conclude that the distance is longer than the hypotenuses of the triangles.
Step-by-step explanation:
A) This is because they are the same shape and have proportionate sizes.
B) This is because if AB = 90 feet, he knows that the distance will be about the same length as the hypotenuses of the triangles.

Answer:
d = 780
Step-by-step explanation:
Remark
You can do this with a proportion which will save you figuring out the rate. I'll do it both ways
Proportion
480/8 = x / 13 Cross Multiply
8*x = 13*480
8x = 6240
x = 780 miles
======================
Remark
Often times we like questions to follow a formula. Here's the formula method.
<u>Formula</u>
d = r * t
<u>Givens</u>
t = 8 hours
d = 480miles
r = ?
480 = r * 8
480 / 8 = r
r = 60
<u>Second part</u>
r = 60 miles per hour
t = 13 hours
d = ?
d = 60*13
d = 780 miles
You do it by cross multiplication so 7*54 and 42*x
378=42x
x=9
