The length of a rectangle is twice its width. Find its area, if its perimeter is 7 1/3 cm. Please help!!
Question
Answer:
Let x be the widthwidth = x
Length is twice its width
length = 2x
Perimeter = length + width + length + width
Perimeter = x + 2x + x + 2x = 6x
Given that perimeter = 7 1/3
6x = 7 1/3Β
x = 7 1/3Β Γ· 6 = 1 2/9
So width = 1 2/9
Length = 1 2/9 x 2 = 2 4/9
Area = length x width
Area = 1 2/9 x 2 4/9
Area = 2 80/81 square cm
