Step-by-step explanation:
The area of a trapezoid is
A = (1/2) h (b1 + b2)
where
h is the height
b1 is length of base 1
b2 is the length of base 2
We are given with the area and assuming that the trapezoid is isosceles, the length of base 1 is
b1 = 4 ft
If the height of the trapezoid is 4.5 feet, it ensures that the shed will fit inside the trapezoid patch of land. Therefore, the height of the trapezoid is 4.5 feet.
Answer:
10 km/h
Step-by-step explanation:
Let s = man's speed and c = speed of current
s + c = 15
c = 2.5 Insert value of c
s + 2.5 = 15 Subtract 2.5 from each side
s = 12.5 km/h
=====
Speed against current
= 12.5 – 2.5
= 10 km/h
The diagonal is 10, so a side is
The area would be 100/2
or 50 m^2.
