Question

A rectangular garden is 6 m longer than its width. If the perimeter is 64 m, how long is it?

Answer 1

Step-by-step explanation:

solution on YOUR website!

let width be x m

length = x+6 m

area = L* W

x(x+6) = 72

x%5E2%2B6x=72

x%5E2%2B6x-72=0

x%5E2%2B12x-6x-72=0

x%28x%2B12%29-6%28x%2B12%29=0

(x+12)(x-6)=0

so x= -12 OR 6

Width cannot be negative

There fore width = 6 m

length = x+6 -------> 6+6=12m
