The width of the rectangle is 43.5 and the length of the rectangle is 87. All together when you add it up it will make 90 cm squared.

If the area is 90 cm

Try

L = length

W = width

==============

L x W = 90

L = 2W + 3

solve for L and W. I had to solve a quadratic by factoring. Check my thinking. Post your work if you get stuck and need further assistance.

Thank you for the help!

This has left me with the equation

2w^2+3w-90=0

I know you must factor this equation but I have tried many pairs of quantities (ex: (2w-45)(w+2) and cannot find one that equals the original equation. Thank you for all your assistance!

Try (2w+15)(w-6)=0

Check my work!!

Yes its right!

w would equal 6 and the length 2w+3 would equal 15

6 times 15 = 90! Thanks sooo much!
