Answer:
63 yd²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where a and b are the parallel bases and h the perpendicular height.
Here a = 8, b = 10 and h = 7, thus
A = 0.5 × 7 × (8 + 10) = 0.5 × 7 × 18 = 63 yd²
The Amanda's house is 6.7 km far from her school.
<u>Step-by-step explanation:</u>
From the given information,
Therefore, It can be determined that it forms the right angle triangle.
It is given that,
The distance between the school and Shereen's house is 2 kilometers.
That is, the height of the triangle = 2 km
The straight-line distance between Amanda's house and Shereen's house is 7 kilometers.
That is, the hypotenuse of the triangle = 7 km
Now, the distance between the Amanda's house and her school is the base of the triangle.
<u>To find the base :</u>
Base =
⇒
⇒
⇒
⇒ 6.7 km
Therefore, the Amanda's house is 6.7 km far from her school.
