Question

the breadth of a reactangular field is twice its length if the area of the field is 1058m find the cost of fencing it at Rs35 per metre

Answer 1

area of a rectangular field = lxb
= 1058m2
ATQ
X x 2x = 1058
2x² = 1058
x² = 1058/2 = 529
x = ✓529 = 23
so length is 23m and breadth = 23x2 = 46m

Perimeter= 2(l+b)
= 2(23+46)
= 138m
cost of fencing = 138 x 35 = 4840
