​

Answer 1

Answer:

Area = hight x length

=4x7=28

Write answer

Answer 2

Given:

• Base of a parallelogram (b) = 4 cm
• Height of a parallelogram (h) = 7 cm

⠀⠀⠀⠀⠀⠀⠀

To find:

• Area of parallelogram?

⠀⠀━━━━━━━━━━━━━━━━━━━━━

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\put(0,0){\line(1,0){5}}\put(0,0){\line(1,5){0.7}}\put(5,0){\line(1,5){0.7}}\put(0.7,3.5){\line(1,0){5}}\put(-1,1.8){\bf 7\ cm}\put(2.3,-0.5){\bf 4\ cm}\end{picture}$

⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{As\;we\;know\;that,}}}$

$\star\;{\boxed{\sf{\purple{Area_{\;(parallelogram)} = Base×Height}}}}$

$:\implies\sf Area_{\;(parallelogram)} = 4×7$

$:\implies\sf Area_{\;(parallelogram)} =28$

$:\implies{\underline{\boxed{\frak{\pink{28\;cm^2}}}}}\;\bigstar$
