Answer 1

let base be b so height is 2b

area of llogram=baseXheight

2bxb=450

b^2=225,b=15cm

h=30cm

Answer 2

$\huge\bf\purple{QUESTION}$

The height of a parallelogram is twice it's base. If the area is 450 cm^2, find its base and height.

$\huge\bf\blue{ANSWER}$

Let the base be b cm.

Height of parallelogram= 2b cm

______________________________________________

Area of parallelogram= Base × Height

$= > 450 = b \times 2b$

$= > 450 = 3b {}^{2}$

$= > b {}^{2} = \frac{450}{3}$

$= > b {}^{2} = 150$

$= > b = \sqrt{150}$

$= > b = 12.24 \: cm$

Height= 2b= 2× 12.24=24.48cm

______________________________________________

Therefore,

Base of the parallelogram is 12.24 cm and height of the parallelogram is 24.48 cm
