The total cost of decorating the garden is found by adding fencing and seed costs. Wire fencing costs 200l rupees, wooden fencing costs 160w rupees and seeds cost 50lw rupees. Therefore, total cost equals 200l + 160w + 50lw.
In the algebraic expression 200l + 160w + 50lw, the terms are 200l, 160w and 50lw. The variables are l and w. The coefficients are 200, 160 and 50. There is no constant term in this expression.
