Question

the side of a rectangle are in the ratio 7 ratio 5 and its perimeter is 96 cm
the length of the rectangle is

Answer 1

Hey Mate, here is your answer :-
Perimeter formula = 2(l+b)
Ratio = 7 ratio 5
Let's take the ratio as x = 7x 5x
Perimeter = 2(7x+5x)=96
= 12x × 2 = 96
= 24x = 96
= x = 96/24
x = 4
l×x = 7 × 4 equals to 28
b×x = 5 ×4 equals to 20
breadth is 20
length is 28

Answer 2

Answer:

28 cm

Step-by-step explanation:

ratio of sides are 7:5

let common multiple be x

then the sides become 7x and 5x

give perimeter is 96 the ,

2(7x+5x)=96

therefore on solving x=4

therefore length is 7x i.e. 28 cm
