Question

a square and a parallelogram have the same area.If a side of the square is 40m and the height of the parallelogram is 20m,find the base of the parallelogram

Answer 1

Hey mate..

Here is ur answer...

Area of a square

=(side)²

=40²

=40×40

=1600m²

Now,

Area of parallelogram

=b×h

Area of square=Area of parallelogram

b×h=1600

b×20=1600

b=1600/20

b=80m

Answer 2

Answer :-

We have a square and a parallelogram have the same area.

area of square = area of parallelogram

Area of square :- $</strong><strong>{</strong><strong>l</strong><strong>}</strong><strong>^</strong><strong>{</strong><strong>2</strong><strong>}</strong><strong>$

$= {(40)}^{2} \\ = 1600 {cm}^{2}$

Area of parallelogram :- base × height

Here height is 20m.

Compare two areas

$</strong><strong>1</strong><strong>6</strong><strong>0</strong><strong>0</strong><strong> = 20 \times height \\ \\ \frac{</strong><strong>1</strong><strong>6</strong><strong>00}{20} = \: height \\ \\ h = </strong><strong>8</strong><strong>0 \: m$

$</strong><strong>\</strong><strong>c</strong><strong>o</strong><strong>l</strong><strong>o</strong><strong>r</strong><strong>{</strong><strong>Red</strong><strong>}</strong><strong>{</strong><strong>Answer</strong><strong>~</strong><strong>i</strong><strong>s</strong><strong>~</strong><strong>8</strong><strong>0</strong><strong>~</strong><strong>m</strong><strong>}</strong><strong>$
