Question

From a rectangular sheet of thin of size 100 cm by 80 cm cut four squares of side 10 from each corner find the remaining part

Answer 1

Answer:

7600 square cm.

Step-by-step explanation:

Total area of rectangle = l×b

=100×80

=8000

Area of 4 squares=4×(10×10)

=4×100

=400

8000-400=7600

hope it helps

Answer 2

AnSwer :-

• $\sf \: The \: area \: of \: remaining \: sheet \: is \: 7600 cm sq.$

GiVen :-

• $\sf \: Length = 100cm$
• $\sf \: breadth = 80cm$
• $\sf \: side = 10cm$
• $\sf \: no. \: of \: square \: cuts = 4$

To Find :-

• $\sf \: Remaining \: part (sheet)\: of \: the \: rectangle.$

Explanation :-

${ \red{\sf {\: Area \: of \: Rectangle :-}}} \\ \\ \sf : \implies \: l \times b \\ \\ \sf : \implies \: 100 \times 80 \\ \\ \sf : \implies \: 8000 \:cm \: sq.$

${ \red{\sf { Area \: of \: the \: Square :-}}} \\ \\ : \implies \sf \: {(side)}^{2} \\ \\ : \implies \sf \: 10 \times 10 \\ \\ : \implies \sf \: 100cm \: sq.$

${\tiny{ \therefore{ \red{\sf{Area \: of \: remaining \: sheet = Area \: of \: rectangle - Area \: of \: square}}}}}$

$\\ \longmapsto \sf \: 8000 - 400 \\ \\ \longmapsto{ \boxed{ \blue{ \sf{\: 7600cm.sq}}}}$

Therefore, area of the remaining sheet is 7600cm.sq
