pls help ne with ths question​

Answer 1

Answer :-

Let base of parallelogram as x than altitude is twice and became 2x.

Here we know area of parallelogram :-

$= base \times height$

Here area is 450 cm^2.

$450 = 2x \times x \\ \\ 450 = 2 {x}^{2} \\ \\ \frac{450}{2} = {x}^{2} \\ \\ {x}^{2} = 225 \\ \\ x = \sqrt{225} \\ \\ x = 15 \: cm$

Base = x = $</strong><strong>\</strong><strong>c</strong><strong>o</strong><strong>l</strong><strong>o</strong><strong>r</strong><strong>{</strong><strong>Red</strong><strong>}</strong><strong>{</strong><strong>1</strong><strong>5</strong><strong>~</strong><strong>c</strong><strong>m</strong><strong>}</strong><strong>$

Altitude = 3x = $</strong><strong>\</strong><strong>c</strong><strong>o</strong><strong>l</strong><strong>o</strong><strong>r</strong><strong>{</strong><strong>Red</strong><strong>}</strong><strong>{</strong><strong>4</strong><strong>5</strong><strong>~</strong><strong> </strong><strong>cm</strong><strong>}</strong><strong>$

Answer 2

Answer:

Let length of parallelogram be x

let altitude be h

Given h = 2x

Area = l X h =450

           x[2x] =450

             2x^2 =450

           x^2 =225 =15^2

             x = 15

length of parallelogram =15

altitude  of parallelogram = 30
