Question

The base and the height of a parallelogram are in ratio 1:3. Its area is 12cm². Find the base and height.​

Answer 1

Answer:

The base=2 m and the height=6 m

Step-by-step explanation:

Given that ,

Base=1 x

Height=3 x

The area of parallelogram 12 cm²

b x h =12

1 x x 3 x =12

3 x²=12

x²=4

x=2

∴the base = 1  x 2=2 m

∴the height=3 x 2=6 m

Answer 2

Answer:

Ans- The base is 2cm and the height is 6cm.

Step-by-Step Explanation:

Since base: height = 1:3

If, base=x cm then height=3x cm

Area of a parallelogram is base x height

So, x X 3x = 12cm²

or 3x² = 12cm²

or x² = 4cm²

or x = 2 cm

Now, base =2 cm and

height= 3x2=6 cm
