Question

. The length and breadth of a rectangle are in the ratio 4 : 3. If its perimeter is 154 cm, find

itsarea.​

Answer 1

Answer:

Let's its lenght & breadth ne 4x and 3x be respectively

Now perimeter of rectangle =2(l+b)

154 cm=2(4x + 3x)

154 cm=2 x 7x

x = 154 x 7/2

x=44 cm

so l = 4x = 4 x 44 = 176

b =3x = 3 x 44 = 132

Area of rectangle = l x b

176 x 132

= 23232 cm
