Question

21. The ratio of length & length & breadth
of a rectangle is 3 : 2. Perimeter of a
rectangle is 740 cm. What is the area of
the rectangle?​

Answer 1

Answer:

Length of rectangle is =x

Breadth of rectangle is = x

ratio of rectangle is 3:2

Length of rectangle is= 3x

Breadth of rectangle is = 2x

Perimeter of rectangle = 2(Length of rectangle+ Breadth of rectangle)

740= 2(3x+2x)

740= 2(5x)

5x = 740/2= 370

5x = 370

x= 370/5 = 74

Length of rectangle = 3 x 74= 222cm

Breadth of rectangle = 2x 74 = 148 cm
