Dimensions: 98 x 98

Step-by-step explanation:

1. Take 98cm and do 98 x 98

2. You get an answer of 9604cm

3. The Dimensions are 98 x 98cm

Answer 2

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
`h^(2)`

divide through by 2

49 =
`h^(2)`

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
