The first one is a dashed line and the second one is solid. Two points for the first one is (1,4) and (0,3). For the second one two points are (0,-3) and (1,0). From build the lines. Finally the first one is where y is greater so shade above the line with points like ( 10,10) or (7,8) in the shaded region. For the second one since y is less or equal to shade below the line with points like (-2,-10) or (-1,-5).
L = rc
= 26.9 * 9*3.14 / 5
= 152.04 to nearest 1/100
Hi U can look for calculators online for help they are very good
220.44=16.7h
220.44/16.7=h
h=13.2
The other parallel side is 44 m
Step-by-step explanation:
Let us revise the formula of the area of a trapezium
, where
and
are its parallel bases- h is its height (The distance between the two parallel bases)
∵ The area of a trapezium is shaped field is 480 m²
∴ A = 480 m²
∵ The distance between two parallel sides is 15 m
∴ h = 15 m
∵ One of the parallel side is 20 m
∴
= 20 m
We need to find 
Substitute all these value in the rule of the area below
∵ 
∴ 
- Multiply the two sides by 2
∴ 
- Divide both sides by 15
∴ 
- Subtract 20 from both sides
∴ 
The other parallel side is 44 m
