Question

The sides of a rectangle are in the ratio of 3:5. Find its sides if the perimeter is 80 cm?
Answer with process

Answer 1

Answer:

length = 25 cm

Breadth = 15 cm

Step-by-step explanation:

Length = 5x

Breadth = 3x

Perimeter =

$2(l + b)$

that is

$2(5x + 3x) = 80$

$2 \times 8x = 80$

$8x = 80 \div 2 = 40$

$x = 40 \div 8 = 5$

Then length =

$5x = 5 \times 5 = 25$

Breadth =

$3x = 3 \times 5 = 15$
