Answer:
8 cm and 10 cm
Step-by-step explanation:
Hello, <em> </em>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.
