Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
From the picture we can infer that:
The side OP is proportional to NP, is half the length of NP.
The side QP is proportional to the side RP, is half the length of RP
The triangle OPQ is proportional to the triangle NPR because the have to proportional sides and the ∠P is the same for both.
Finally, if the triangles are proportional, the side OQ is proportional to the side NR. (is half the side of NR)
Answer:
l=20m
w=5m
Step-by-step explanation:
Let "l" be the length of the rectangle &
let "w" be the width of the rectangle
l=15+w
P=2(l+w)
50m=2(15m+w+w)
50m=2(15+2w)
50m=30m+4w
20m=4w
w=5m
l=15m+w
l=15m+5m
l=20m
Proof:
P=2(l+w)
P=2(15m+w+w)
50m=2(20m+5m)
50m=40m+10m
50m=50m
