Question

the sides of the rectangle are in the ratio 3:7 and it's area is 1029msq find the dimension of the rectangle and then perimeter

Answer 1

Answer:

Let common ratio be x

Then dimensions will be 3x and 7x.

Area of rectangle=lb

1029=3x•7x

1029=21x²

x= 49m

Thus,

Length=49•3

=147m

Breadth=49•7

=343m
