Question

A rectangular garden is 15 ft longer than it is wide. Its area is 450

ft^2
. What are its dimensions?

Width equals =------

Length equals=-----

Answer 1

Width= 15ft and Length= 30 ft

Explanation:

Length=15+w

Area=450 ft square

(15+w)(w)=450

w²+15w=450

w²+15w-450=0

(w+30)(w-15)=0

w= -30, 15

width can't be negative so possible answer is 15 ft

Length = 15+15=30 ft
