let the sides of rectangle = x
now length = 9x
width = 7x
2(l+b) = 144
2( 9x + 7x ) = 144
2 (16x) = 144
32x = 144
x = 144/32 = 4.5cm
length = 9×4.5 = 40.5 cm
width = 7 × 4.5 = 31.5 cm
now length = 9x
width = 7x
2(l+b) = 144
2( 9x + 7x ) = 144
2 (16x) = 144
32x = 144
x = 144/32 = 4.5cm
length = 9×4.5 = 40.5 cm
width = 7 × 4.5 = 31.5 cm
