Answer:
Width is 18 inches
Perimeter is 99 inches
Area is 567 square inches
Step-by-step explanation:
The ratio of width to length is 4 : 7
The length is 31.5 inches
The width = (31.5 ×4) ÷ 7 = 18 inches
Perimeter = 2(length + width)
Perimeter = 2(31.5 + 18) inches = 99 inches
Area =length × width
Area = 31.5 inches × 18 inches = 576 square inches.

Answer:
Step-by-step explanation:
2 1/2 + x = 5 1/3 Change the mixed numbers to improper fractions
5/2 + x = 16/3 The lowest common multiple is 6. Multiply by 6
5*3 + 6x = 16*2
15 + 6x = 32 Subtract 15 from both sides.
6x = 32 - 15
6x = 17 Divide by 6
6x/6 = 17/6
x = 2 5/6
Check
5/2 + 17/6 = 16/3
15/6 + 17/6 = 32/6
32/6 = 32/6 The question checks.
