Answer:
If a = 5 and b = 3, then that means 2a - 3b + 3a = 16
Step-by-step explanation:
2a - 3b + 3a
(2×5) - (3×3) + (3×5)
10 - 9 + 15 = 16
Answer:
Perimeter = 2l + 2w //l=length, w=width
l = 44 + w
Now substitute 44 + w in place of l in the above equation and you have
2(44 + w) + 2w = 288
=> 88 + 2w + 2w = 288
=> 88 + 4w = 288
=> 4w = 200
=> w = 50 and l = 44 + 50 = 94
2*94 + 2*50=288
