Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
3 4/5 + (3 4/5 - 1/2) =
19/5 + (19/5 - 1/2) =
19/5 + (38/10 - 5/10) =
19/5 + 33/10 =
38/10 + 33/10 =
71/10 which equals 7 1/10 tons <==
