3 : 4 = 2700 : 3600
sum the parts of the ratio : 3 + 4 = 7
divide 6300 by 7 to obtain 1 part
= 900 ← 1 part
3 parts = 3 × 900 = 2700
4 parts = 4 × 900 = 3600
note that 2700 + 3600 = 6300

Answer:
27 inches
Step-by-step explanation:
Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches
Perimeter of rectangle = 2(L + W)
L = 11 in.
W = 7 in.
Perimeter of rectangle = 2(11 + 7) = 36 in.
Let perimeter of the triangle be represented by x
Therefore:
36 + x = 63
Subtract 36 from each side
x = 63 - 36
x = 27
Perimeter of triangle = 27 inches
