Question

The length of rectangle of parimetar 64cm is 5/3rd of its breath .find the area of rect Rectangle

Answer 1

breadth = x

length = 5x/3

2(x+5x/3) = 64

8x = 32×3

x = 12

Length = 20

Area = 12×20 = 240

Hope it helps u :-)

Answer 2

Let Breadth of rectangle be X cm.

Length of rectangle = 5 X/3 cm

Perimeter of rectangle = 64

2 ( L + B ) = 64

5X/3 + X = 32

5X + 3X = ( 32 × 3 )

8X = ( 32 × 3 )

X = ( 32 × 3/8 )

X = 12 cm

Breadth of rectangle = X = 12 cm

And,

Length of rectangle = 5X/3 = 20 cm.

Area of rectangle = Length × Breadth = 20 × 12 = 240 cm².
