Answer: 38 cm
Step-by-step explanation:
Given : The expression 2/ +2w is used to find the perimeter of a rectangle with length / and width w .
For length 15 cm and width 4 cm, the perimeter of a rectangle will be :-
Perimeter :
Hence, the perimeter of a rectangle with length 15 cm and width 4 cm is 38 cm.

Answer:
a) 7a/8; b) 5a/8
Step-by-step explanation:
Given:
AP = 2PQ = 2QB
Calculations:
1. A to the midpoint of QB
a = AP + PQ + QB
If 2PQ = 2QB.
PQ = QB and
AP = 2PQ
∴ a = 2PQ + 2PQ = 4PQ
PQ = a/4
AP = 2PQ = a/2
Let M be the midpoint of QB.
AM = AP + PQ + QM
= a/2 + a/4 + a/8
= 7a/8
2. Midpoints of AP and QB
Let N be the midpoint of AP
NM = NP + PQ + QM
= a/4 +a/4 + a/8 =
= 5a/8
