Question

the area of a parallelogram is 72 cm2 and it's altitude is twise the corresponding base .The length of the base is .
​

Answer 1

Answer:

base = 6 cm and height = 12 cm

Step-by-step explanation:

Area of parallelogram = 72 cm²

base = x cm

height = 2x cm

Area of parallelogram = base × height = 72 cm²

or 2x × x = 72

or 2x² = 72

or x² = ⁷²/2

or x² = 36

or x = ± 6 cm

But length cabbie be negative, so x = 6 cm

Therefore, base = 6 cm and height = 12 cm

Answer 2

Given : -

The area of a parallelogram is 72cm² and it's altitude is twice the corresponding base .

To Find : -

Length of the Base is = ?

Formula Used : -

Area of Parallelogram is = Base × Height

Step-by-step Explanation : -

Area = 72cm²

Height/Altitude = 2b

By Using the above Formula : -

72 = b × 2b

2b² = 72

b² = 36

b² = √36

b = 6cm

Therefore , the length of the base is 6cm..
