Step-by-step explanation:
You would divide 100/20 and get 5. then u would multiply 9 times 5 equals 45 then add a decimal to get ur answer 0.45
The answer to your question would be y2 +5y.
They tell you that the length is 7 inches and that it is 2 inches more than the width therefore you can conclude that: length = 7 and the width = 5
you can plug the values given into the formula listed below:
A = lw
A = 7 x 5
A = 35
