Question

the perimeter of the rectangle is 70cm. it's length exceeds its breath by 5cm. then find the length and breadth of the rectangle​

Answer 1

$\blue\bigstar\sf\pink{Answer:}$

Let the breadth of the rectangle be x cm.

According to the question,

Length =(x+5)cm.

Perimeter of rectangle =2(length+breadth)

2[(x+5)+x]cm

2(2x+5)cm

Now, 2(2x+5)=70

2x+5=35

2x=35-5

2x=30

x=15

Hence,breadth of the rectangle is 15cm and length is (15+5)cm=20cm.
