Answer 2

Correct Question:

Find the sides of a rectangular field whose perimeter is 90 cm and sides are in the ratio 5:4.

Answer:

♦ Length of a rectangular field = 25 cm

♦ Breadth of a rectangular field = 20 cm

Step-by-step explanation:

Let the sides of a rectangular field be 5x and 4x respectively.

✰ Perimeter of a rectangle = 2( l + b )

Where,

l is the length of a rectangle.

b is the breadth of a rectangle.

Putting the values,

• 90 = 2( 5x + 4x )
• 90 = 2 × 9x
• 9x = 90/2
• 9x = 45
• x = 45/9
• x = 5

Finally,

• Length of a rectangular field = 5 × 5
• Length of a rectangular field = 25 cm

• Breadth of a rectangular field = 4 × 5
• Breadth of a rectangular field = 20 cm
