Area of a rectangle = length x width
For this postcard:
length = 4 in
width = (3+b) in
area = 24 in^2
Substitute into the area formula:
24 = 4 x (3+b)
24 = 12 + 4b
24 - 12 = 4b
12 = 4b
b = 3 in
Therefore:
the length of the postcard = 4 inch
the width of the postcard = b+3 = 3 + 3 = 6 inch
Answer:
one hour.
Step-by-step explanation:
by subtracting 24 from 36, you arrive at 12, which when multiplied by 5 gives you 60. 60 minutes equals one hour.
