Question

Alice’s backyard is a rectangular piece of property that is twice as long as it is wide. The total area of her yard is 1,000 m2. What is the approximate width of her backyard? A = lw 11. 2 m 15. 8 m 22. 4 m 44. 8 m.

Answer 1

Let l represent the length and w represent the width of the yard.

The property is twice as long as it is wide. hence:

l = 2w

The total area of her yard is 1,000 m². hence:

lw = 1000

2w(w) = 1000

w² = 500

w = 22.4 m

Hence the approximate width of her backyard is 22.4 m
