Answer:
Perimeter of a rectangle= 2(l+b).
86= 2(b+7+b).
43= 2b+7.
2b= 36.
b= 18m.
l= b+7.
l= 18+7 = 25m.

Answer:
The breadth is 25
Step-by-step explanation:
86 = 2(w + 7) + 2w
Distribute:
86 = 2w + 14 + 2w
simplify:
86 = 4w + 14
subtract 14:
72 = 4w
divide by 4:
18 = w
l = 18 + 7
l = 25
check:
2 * 25 + 2 * 18 = 86
50 + 36 = 86
86 = 86
