Question

Explain how you could use the dimensions of a reduced rectangle and one given measurement of an original rectangle to find a missing measure?
Please and thank you

Answer 1

You could use a proportion and cross-multiply. For example, if the reduced rectangle had a length of 3 and a width of 5, and then the one measurement of the original rectangle is length of 7, you could set a proportion like:
3/5 = 7/x

Then, cross multiply to solve for x, and that sound give the missing measure. 

Answer 2

The following information should be considered:

• Here we can proportion and cross-multiply.
• For example, if the reduced rectangle had a length of 3 and a width of 5,
• And then the one measurement of the original rectangle is length of 7,
