Answer: 14 and 7
Step-by-step explanation:
The formula for calculating the area of a rectangle is given as :
A = width x length
From the question:
A = 98
Let the height be h , then since the width is double the height , this means that width = 2h
Substituting into the formula , we have
A = 2h x h
98 = 2[tex]h^{2}[/tex]
divide through by 2
49 = [tex]h^{2}[/tex]
Therefore :
h = 7
Since the length is 7 , then the width is 2 x 7 = 14
Therefore : the dimensions of the rectangle is 14 by 7
