Question

the length of a rectangle is three time of its width and the perimeter of rectangle is three times the perimeter of square whose area is 100 . what is the area of rectangle?

Answer 1

Answer:

Let the length of the rectangle be x

Breadth = x/3

Perimeter = 56 m

2(l+b) = 56 m

l+b = 28 m

x+ x/3

=28m

4x = 80 m

x = 21 m

length = 21 m Breadth = 7 m
