Susan enlarged to scale a rectangle with a height of 4cm and length of 11 cm her computer. the length of the new rectangle is 16.5 cm . find the new height of the rectangle

h=6 cm

Step-by-step explanation:

Hi,

The key point here is to understand that both of these rectangles have the same ratio, namely  

Let us draw the rectangle so that we all can visualize it better (Check it out below).

2) Setting the proportion, writing a rule of three, already like two fractions. In the Numerators the length of both rectangles, in the Denominators we will write the heights: (Check it out)

3) Doing the calculations:

(In case of code error, you may check it below too)

the answer is ! ?

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
