.
first we'll find area of trapezium.
area of trapezium = 1/2×height×(sum of parellel sides of the trapezium)
area of trapezium =1/2×4×(13+24)
area of trapezium =1/2×4×37
area pf trapezium = 74in²
now area of rectangle.
area of rectangle = length ×width
area of rectangle= 24in×7in
area of rectangle =168 in²
area of the figure= 74in²+168in²
area of figure=242in²
Answer:
y = 2x when x = -11
y = 2(-11)
y = -22
f(x) = -3x + 6 when x = 1
f(x) = -3(1) + 6
f(x) = -3 + 6
f(x) = 3

Step-by-step explanation:
Answer:
275 minutes 12 seconds
Step-by-step explanation:
Given that :
slowest running time per mile = 9 minutes and 14 seconds
fastest running time per mile = 7
minutes and 58 seconds.
To estimate the time taken to run 16 miles ;
Obtain the Average of the two run times :
(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second
Hence it takes an average of 17 minutes 12 seconds per mile
Time taken to run 16 miles :
((17 * 60) + 12) * 16 = 16512 seconds
16512 / 60 = 275 minutes 12 seconds
