Answer:
Step-by-step explanation:
Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:
d = rt or d = 2 1/3(3)
Multiply:
Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:
11 3/8 - 7 =
D) 20.
First find the value of x using Pythagoras theorem:
10^2 = x^2 + (2x)^2
5x^2 = 100
x^2 = 20
x = √20
= 2√5.
So the area of triangle
= 1/2 * base * height
= 1/2 * 2x * x
= x^2
= (2√5)^2
= 20.
Hoped this helped.
