Question

Dan enlarged the size of a rectangle to a height of 22.4 in. What is the new width of the rectangle if it was originally 5.6 in tall and 1.4 in wide

Answer 1

The new width is 5.6 in

Explanation:

Given

New

`H_2 = 22.4`

Old

`H_1 = 5.6`

`W_1 = 1.4`

Required

The new width

This is calculated using the following equivalent ratio

`H_2 : W_2 = H_1 : W_1`

`22.4 : W_2 = 5.6 : 1.4`

Express as fraction

`W_2/22.4 = 1.4/5.6`

Multiply both sides by 22.4

`W_2= 1.4/5.6 * 22.4`

`W_2= 5.6`
