Answer:
100 inches
Step-by-step explanation:
A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.
This is calculated using proportion
Side length/Perimeter
Hence:
Side length of smaller triangle = 19 inches
Perimeter of smaller triangle = 95 inchee
Side length of larger triangle = 20 inches
Perimeter of larger triangle = x
19/95 = 20/x
Cross Multiply
19x = 95 × 20
x = 95 × 20/19
x = 100 inches
The perimeter of the larger triangle = 100 inches
It's just telling you to multiple like 9×1=9 9×2=18 and so on.
Answer:
It isn't necessary but having a positive coefficient for
