Question

The side of a rectangular are in the ratio 7:5 and its perimeter is 96cm. The length of the rectangel is.

Answer 1

Answer:

28cm, 20 cm

Step-by-step explanation:

2multiply 7x+5x=96 . 14x+10x=96. 24x=96.x=4. side =7 multiply 4=28cm. 5time4=20.

Answer 2

Step-by-step explanation:

ratio of the sides of rectangle =7:5

let length (l) =7x, breadth (b) =5x

perimeter of rectangle =96cm (given)

2(l+b)=96

2(7x+5x)=96

2(12x)=96

24x=96

x=96/24

x=4

length of rectangle =7x

=7*4

breadth of rectangle =5x

=5*4

length of rectangle =28 cm

breadth of rectangle =20 cm

hope it helps you!!
