Rectangle A is a scale drawing of Rectangle B and has 25% of its area. If rectangle A has side lengths of 4 cm and 5 cm , what are the side lengths of rectangle B ?

8 cm and 10 cm

Step-by-step explanation:

Hello, I can help you with this.

Step 1

According to the question there are two rectangles A and B,

Rectangle A is a scale drawing of Rectangle B and has 25% of its area

in other words

Step 2

Let

Rectangle A

length (1)= 4 cm

length (2)= 5 cm

put this value into equation 1

Now, we know the area of rectangle B, to know its length we need to formule other equation

Step 3

the ratio between the lengths must be constant, so the ratio of A must be equal to ratio in B, then

Step three

using Eq 1 and Eq 2 find the lengths

put the value of length(1B) into equation (2)

Now, put the value of length(2B) into equation 3 to know length (1B)

I really hope this helps you, have a great day.
