Question

10) The breadth of a rectangular park is of 48 m. If 3 km 72 m long wire is required
for fencing it, find the length of the park.
6. The perimeter of a square is double that of a rectangle. If perimeter of the square is 120 m, and length and breadth of the rectangle are in the ratio 3:2.find the breadth of the rectangle.​

Answer 1

b=48m

long wire required for fencing= perimeter of the rectangule

=3km 72m= 3072m

perimeter= 2(l+b)

3072=2l+2b

3072-96= 2l

2976÷2=l

1488=l
