Answer:
Here
perimeter=76
length =4a+5
breadth=2a-3
we know,
perimeter=2(length+breadth)
76=2(4a+5+2a-3)
76=2(7a+2)
76=14a+4
76-4=14a
72=14a
72÷14=a
a=5.14
Answer:
do u take links bcs i can give u a link to the answer if u want
Let the speed of the current equal c
and the speed of the boat in still water equal b.
b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c
The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph
4,000 +000 +00 + 0 is stander form for four thousand
