Question

A rectangle has length 40cm breadth 20cm . How many squares with side10cm can be formed from it

Answer 1

Answer:

8

Step-by-step explanation:

Given---> Length and breadth of rectangle are 40cm and 20cm and side of square to be formed is 10 cm.

To find---> ATQ,

Length of rectangle = 40cm

Breadth of rectangle = 20 cm

We know that ,

area of rectangle = length × breadth

= 40 × 20

= 800 cm²

Area of square = Side²

= ( 10 )²

= 100 cm²

Number of square formed

= Area of recangle / Area of square

= 800 / 100

= 8

Additional information---->

1) Perimeter of square = 4 ( sides )

2) perimeter of rectangle = 2 ( length + breadth )

3) Area of triangle = ( base × height ) / 2

4) Area of ||gm = base × height

Answer 2

$\bf{\Huge{\boxed{\rm{\blue{ANSWER\::}}}}}$

$\bf{Given}\begin{cases}\sf{Length\:of\:rectangle\:=\:40cm}\\ \\\sf{Breadth\:of\:rectangle\:=\:20cm}\\\\ \sf{Side\:of\:square\:=\:10cm}\end{cases}}$

$\bf{\Large{\underline{\bf{To\:find\::}}}}$

The number of squares.

$\bf{\Large{\underline{\tt{\red{Explanation\::}}}}}$

We know that;

$\longmapsto\begin{cases}\rm{\pink{Area\:of\:rectangle\:=\:Length*Breadth}}\\ \\\rm{\orange{Area\:of\:square\:=\:Side*Side}}\end{cases}}$

A/q

$\implies\tt{Number\:of\:squares\:=\:\frac{Area\:of\:rectangle}{Area\:of\:square} }$

$\implies\:\tt{Number\:of\:squares\:=\:\frac{Length*Breadth}{(Side)^{2} } }$

$\implies\tt{Number\:of\:squares\:=\:\frac{40*20}{(10)^{2} } }$

$\implies\tt{Number\:of\:squares\:=\:\frac{800}{100} }$

$\implies\tt{Number\:of\:squares\:=\:\cancel{\frac{800}{100} }}$

$\implies\tt{\pink{Number\:of\:squares\:=\:8}}$
