Question

split the following shapes into rectangles and find their areas (the measures are given in centimetres )

*this is the first part only, there are three parts* ​

Answer 1

Answer:

Area of the vertical triangle 24 sq cm

Area of the horizontal triangle 20 sq cm

Step-by-step explanation:

Area of the vertical triangle = l×b

= 12 × 2

= 24

Area of the horizontal triangle = l×b

= 10 × 2

= 20

Answer 2

$\Huge{\textbf{\textsf{{\color{navy}{an}}{\purple{sw}}{\pink{er}}{\color{pink}{:}}}}}$

$\bf{Area~of~the~figure:}$

$\sf{~~~~~~Area~of~vertical~rectangle+ Area~of~horizontal~rectangle}$

$\bf{Formula~for~area~of~rectangle:}$

$\sf{~~~~~~l×b}$

$\bf\therefore{{\underline{Area~of~vertical~rectangle}}}$

$\sf{l=12cm~~~~~~b=2cm}$

$\sf{~~~~~~ l×b}$

$\sf{:→ 12×2}$

$\sf{:→ \color{red}{\underline{\boxed{\bf 24cm^{2} }}}}$

$\bf{{\underline{Area~of~horizontal~rectangle}}}$

$\sf{l=8cm~~~~~~b=2cm}$

$\sf{~~~~~~ l×b}$

$\sf{:→ 8×2}$

$\sf{:→ \color{red}{\underline{\boxed{\bf 16cm^{2} }}}}$

$\bf\therefore{{\underline{Area~of~the~figure:}}}$

$\sf{~~~~~~Area~of~vertical~rectangle+ Area~of~horizontal~rectangle}$

$\sf{:→ 24+16}$

$\sf{:→ \color{red}{\underline{\boxed{\bf 40cm^{2} }}}~~~~~{\huge{✓}}}$
