Question

The football field is rectangular in shape, and length of the longer side is 10 cm and
the width is 70 mm. Find the area of the field.​

Answer 1

Answer:

length= 10cm

breath= 70mm= 7cm

area of rectangular feild= L×B

= (10×7)cm^2

=70cm^2

Hope it helps........

Answer 2

$\sf Given \begin{cases} & \sf{Length\;of\;football\;field = \bf{10\;cm}} \\ & \sf{Breadth\;of\;football\;field = 70 mm = \bf{7\;cm}} \end{cases}$

To find: Area of rectangular football field?

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━

$\setlength{\unitlength}{0.9cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 10 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 7 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

⠀⠀⠀

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

$\star\;{\boxed{\sf{\pink{Area_{\;(rectangle)} = length \times breadth}}}}$

Therefore,

⠀⠀⠀

$:\implies\sf Area_{\;(football\;field)} = 10 \times 7$

$:\implies{\underline{\boxed{\frak{\purple{Area_{\;(football\;field)} = 70\;cm^2 }}}}}\;\bigstar$

$\therefore\;{\underline{\sf{Hence,\;Area\;of\;rectangular\;football\;field\;is\; \bf{70\;cm^2}.}}}$

$\qquad\qquad\boxed{\underline{\underline{\pink{\bigstar \: \bf\:More\;to\;know\:\bigstar}}}}$

⋆ Rectangle: A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The opposite sides of the rectangle are equal in length.

⠀⠀⠀

• Perimeter of Rectangle = 2(length + breadth)

• Area of Rectangle = length × breadth

• Diagonal of Rectangle = √(length)² + (breadth)²

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━

⋆ Square: A square is a two-dimensional plane figure with four equal sides and all the four angles are equal to 90 degrees.

⠀⠀⠀

• Area of square = side × side

• Perimeter = 4 × side

• Diagonal of square = √2 × side
