The length of longer side of gate is $2.65 (2 d p) m$ $2.65(2dp) m$

Explanation:

The angle between diagonal strut (D) horizontal side of gate is $θ = 28^{0}$ $theta=28^0$ .

So strut forms a right triangle with horizontal side(H) and vertical side(V) of the rectangular gate.

$sin θ = \frac{V}{D} or V = D \cdot sin θ = 3 sin 28 = 1.41 (2 d p) m and cos θ = \frac{H}{D} or H = D cos θ = 3 cos 28 = 2.65 (2 d p) m$ $sin theta = V/D or V= D*sin theta= 3 sin28 = 1.41 (2dp) m and cos theta = H/D or H = D cos theta= 3 cos 28 = 2.65(2dp) m$

The length of two sides of gate are $1.41 (2 d p) m and 2.65 (2 d p) m$ $1.41 (2dp) m and 2.65(2dp) m$

So the length of longer side of gate is $2.65 (2 d p) m$ $2.65(2dp) m$ .[Ans]
