Question

Solve the following problems by forming equations. ​

Answer 1

Answer:

1) 4/5

2) l=25m and b=10m

Step-by-step explanation:

1) let the fraction be x

according to question

x-1/4=11/20

x=11/20+1/4

x=11+5/20

x=4/5

2)let breadth of rectangle be x

so, length = 5/2x

perimeter=70m

perimeter of rectangle=2×(l+b)

70=2(5/2x+x)

70=2(5x+2x/2)

70=7x

x=10

so, length=25 and breadth=25
