Question

the length of a rectangle is 20 CM more than its breadth if the perimeter is 100 cm find the dimension of the rectangle​

Answer 1

Answer:

35 x 15

Step-by-step explanation:

let the breadth = x cm

then perimeter =

100 = 2(x +20+x)

100 = 4x + 40

4x = 60

x = 15

length = 35cm

breadth = 15cm

Answer 2

Answer:let breadth be x then length be 20+x according to the question

Perimeter of rectangle =2 ( l+b)

100=2 (20+x+x)

100/2=20+2x

50-20=2x

30/2=x

x=15
