Marks: +1, -0

A wire of length 60 m is used to enclose a field which is in the shape of a right-angled triangle. The area of the field is 150

m ^2

. Then, the largest side of the field has a length of

Solution:

(3) If ft and x are the height and base of the triangle, then according to the question,

1/2

hx = 150
⇒ hx = 300
and h + x +

√{h^2 + x^2}

= 60
By hit and trial method, we take
h = 20 m, x = 15 m
Hence, largest side =

√{20^2 + 15^2}

√625

= 25 m
