Question

the perimeter of a rectangle is 70 cm.If its lemgth exceed s its breadth by 5 cm . Find the dimensions of rectangle

Answer 1

breadth x
length x+5

2(x +x+5) 70
4x+10. 70
x=70-10/4
x=15
breath 15cm
length 20cm

Answer 2

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.
