Answer:1968ft^2
Step-by-step explanation:
Perimeter(p)=178feet
P=2L+2w
178=2L+2w
178=2(L+w)
L+w=178 ➗ 2
L+w=89.............(1)
W+7=L
L-w=7...................(11)
L+w=89... ..........(1)
L-w=7...................(11)
Subtract (11) from (1)
2w=89-7
2w=82
w=82 ➗ 2
w=41 width=41feet
Substitute w=41 in (11)
L-w=7
L-41=7
L=7+41
L=48feet
Area= length x width
Area=48 x 41
Area=1968ft^2
Area of triangle = 0.5 * base * height
30 = 0.5 * 6 * base
30 = 3 * base
so , base = 10 inch
Answer: 31.5
Step-by-step explanation:
9 is 100% so if you times that by 3 you get 27 and 50% of 9 is 4.5 if you add that to 27 you get 31.5
