#12m# long and #5m# wide

Explanation:

We know that area is length times width. In this case, the answer is #60# so you need factors that multiply to #60# like:

#4 xx 15, 6 xx 10 and 5 xx 12.#

The Pythagorean Theorem also tells us that that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
#13^2 = 169#.

Looking at your list of factors, #4 and 15# won't work
(#16 + 225 = 241#) and neither do 6 and 10 (#36 + 100 = 136#).

#5 and 12# reveal #25 and 144#, which do add to #169.#

#:.# the length is #=12m# and the height #5m.#
