Answer:
A=140m² and P=54m
Step-by-step explanation:
In order to find the perimeter or area, we are going to first need to find the lenghts of the missing sides. There are two of them, we are going to refer to one as the shorter one and the other as the longer one.
Shorter One = 12-8
Shorter One = 4
Longer One = 15-5
Longer One = 10
From this we can then add the side lengths to find the perimeter of the figure.
Perimeter=5+15+12+8+4+10
Perimeter=20+20+14
Perimeter=54
The perimeter of the figure is 54m, therefore we can eliminate two of the answer choices.
Next, we need to find the area of the figure. The easiest way is to cut the figure into two pieces, I chose to do it by cutting a long rectangle, and then add their areas together.
A=(5*12)+(10*8)
A=60+80
A=140
Therefore the correct answer choice is A=140m² and P=54m
Scale 1: 250,000 literally means for 1cm you calculated on the map it is magnified by 250,000 times. So if that road is 4-6cm, you just multiply it by 250,000 times and you get 1,150,000 cm.
Since you wanted to be in Km. the 100 cm is 1 meter and 1000 meters is 1 km. Therefore, 1,150,000/ 100 x 1000 = 11.5 km . Answer: 11.5 km.
(a) angle TPR = 90° - 30° = 60°
Reason: because the PTR is a right angled triangle.
(b) sin 30° = PR/14
PR = sin 30° × 14 = 7in.
(c) tan 30° = 7/TR
TR = 7/tan30° = 7 / (1/(#3))
= 7#3 in.
# : square root
(d) sin 45° = 7/PQ
PQ = 7/sin 45° = 7 / (1/(#2))
= 7#2 in.
Hope it helped!
Answer:
I think B but I'm not sure
Step-by-step explanation:
Count the squares
6 x 3.5
Area = 6 x 3.5
Area = 21
Perimeter = 6 + 6 + 3.5 + 3.5
Perimeter = 19
