Question

the perimeter of a rectangle is 100 m and its breath is 15 m find its length​

Answer 1

Answer:

let length=x

breadth=15m ; perimeter=100m

perimeter of rectangle=2(l+b)

=

$2(x + 15) = 100 \\ 2x + 30 = 100 \\ 2x = 70 \\ x = 35$

Answer 2

Answer:

we know that Perimeter of rectangle is 100cm =2(a+b)

given breadth=15cm

• 2(15+a)=100
• 15+a=50
• a=50-15
• a=35

Step-by-step explanation:

therefore length of rectangle is 35
