Question

The measure of two adjacent sides of a rectangle are in the ratio 4:3. If the perimeter of the rectangle 686 cm find its length and breadth. ​

Answer 1

Ansjust take the sides as 4x and 3x

the perimeter of the rectangle is 686 cm

the formula for the perimeter of the rectangle is 2(l+b)

substitute the values,u get:

2(4x+3x)=686

7x=686/2

x=343/7

therefore x=49

l=4x=4*49=196

b=3x=3*49=147

Step-by-step explanation:

Answer 2

Answer:

Length=4x

Breadth=3x

Perimeter=686 cm

We know that perimeter=2(length+breadth)

So,2(4x+3x)=686

2(7x)=686

14x=686

x=686÷14

x=49

So,length=4x=4(49)=196

Breadth=3x=3(49)=147
