Question

The base and height of parallelogram are in ratio 1:3. It's area is 12sq cm. Find the base and height

Answer 1

Answer:

2 & 6 cm

Step-by-step explanation:

Let base be 'x' cm

n height be '3x' cm.

Area of parallelogram = base × height

12 cm^2 = (xcm) × (3xcm)

12 cm^2 = 3x^2 cm^2

4 = x^2

=> x = 2

Therefore; base = 2cm

height = 6cm.

Answer 2

Step-by-step explanation:

Let, base be 1x

height be 3x

Then , Area of parallelogram = b×h

• 12cm² = 1x × 3x
• 12cm² = 3x²
• 12÷3 = x
• 4 = x
• x = 4

therefore, base

• 1x = 1×4 = 4cm

and height

• 3x = 3×4 = 12cm
