Question

A rectangular garden is 10 ft longer than it is wide. Its area is 1575 ft. What are its dimensions?

Answer 1

Answer:

W=35, L=45

Step-by-step explanation:

L= W+10

L×W=1575

(W+10)W=1575

W^2+10W=1575

W^2+10W-1575=0

(W-35)(W+45)=0

W=35 or W=-45 (cant be negative) so has to be 35

And L = W+10=45
