Answer:
30cm2
Step-by-step explanation:
first find area of triangle
A = 1/2 *b*h
A = 1/2 * 9 * (4 + 3 +1)
I got the 3 from the other side of the cut out rectangle.
1/2 * 9 * 8 = 36
next find area of cut out rectangle
A = l * w
A = 3 * 2 = 6
Last, subtract area of triangle - area of cut out rectangle
36-6 = 30cm 2

now in your case what would be the answer ?
7/12 of 1 hour:
1 hour = 60 min.
7/12 * 60
7 * 5 = 35
Francis ran 2 1/2 miles in 35 min.
2 1/2 = 5/2
5/2 miles = 35 min
x miles = 60 min
(Cross Multiply)
5/2 * 60 = 35x
5 * 30 = 35x
150 / 35 = x
x = 30 / 7 = 4 2/7 miles
Francis ran 4 2/7 miles in one hour.
