Answer:

Correct Question:

The base of a parallelogram is twice its height. If its area is 800 cm², find its height and base.

Required Solution:

Given:

The base of a parallelogram is twice its height.

Its area is 800 cm².

To calculate:

Height and base

Calculation:

Let the height of the parallelogram be x cm.Therefor,its base becomes 2x cm.

We know that,

Area of parallelogram = length × breadth

According to the question:

→ 800 = (x) × (2x)

→ 800 = 2x²

→ x² = \dfrac{800}{2}

2

800

→ x² = 400

→ x = \sqrt{400}

400

→ x = 20 cm [Height]

Height = x = 20cm

Base = 2x = (2×20) = 40cm
