Question

The length of a rectangle is 7/5 of its breadth. If it's perimetre is 48cm, then what is its length
$\frac{7}{5}$
​

Answer 1

Answer:

14 cm

Step-by-step explanation:

let,breadth=x

then length=7x/5

perimeter=48 cm

2(length+breadth)=perimeter

2(7x/5+x)=48

(7x+5x)/5=48/2

12x/5=24

12x=24×5

12x=120

x=120/12

x=10cm

breadth=10cm

length=7/5 of its breadth

=7/5×10

=14 cm

Length = 14 cm
