To find the actual area or perimeter, you need to make the centimeters into meters. But, you have to use the scale. ( 1cm : 320m )
L=13.5
You need to multiply 13.5 and 320 (because that's how much more there is in the other model or the meter's shape)
13.5 * 320 = 4,320.
The actual Length in meters is 4,320.
Do the same with W.
3.3 * 320 = 1,056.
<span>Now you have the real lengths.
</span><span>Area = L * W
</span>So you put in the real measurements.
Area = 4,320 * 1,056
Area = 4,561,920.
Perimeter is the sum of all sides, so Sum up all of the sides' measurements.
Hope this helps <3

this is what i got. i am sorry if it is wrong.
Answer:
15
Step-by-step explanation:
70÷14=5
5×3=15
So the ratio would be 70:15 which can be simplified to 14:3
The first step to solve this problem is to find the area of
the rectangular piece of fabric.
A of triangle = bh/2
A = (14 cm) (6 cm) /2
A = 84 cm^2 / 2
A = 42 cm
And since there are 31 pieces of the fabric, the total area
of all the pieces of fabric is:
31 pieces of fabric x 42 square centimeters per piece =
1,302 square centimeters
To computer how many congruent triangular patches can be
cut, you have to divide the total area of the fabric pieces with the area of
the congruent triangle:
1,302 square centimeters / 21 square centimeters = 62
Therefore, Leia can cut 62 patches.
The answer is <u><em />A</u><u /> but im not 100% sure
