Question

The area of a table is 28 sq m and its length is 7 m. What is the width?

Answer 1

Answer:

4

Step-by-step explanation:

Area=l*w

28=7*w

w=28/7=4

Answer 2

ANSWER :

★ If the area of a table is 28 sq. m and its length is 7 m, then the width of the table = 4 m.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

SOLUTION :

❖ Given :-

• Area of the rectangular table = 28 sq. m

• Length of the rectangular table = 7 m

❖ To Find :-

• Width of the rectangular table = ?

❖ Required Formula :-

$\bigstar \: \boxed{ \bold{Area \: \: of \: \: a \: \: rectangle = Length \times Width}}$

❖ Calculation :-

$\bigstar \: \: \sf{Area \: \: of \: \: the \: \: table = Length \times Width} \\ \\ \sf{ \large{ \implies \: 28 = 7 \times Width}} \\ \\ \sf{ \large{ \implies \: Width = \dfrac{28}{7}}} \: \: \: \: \\ \\ \sf{ \large{ \therefore \: \: \underline{ \:Width = 4 \: }}}$

• Hence, Width of the table = 4 m

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

VERIFICATION :

❖ We have :-

• Area = 28 sq. m

• Length = 7 m

• Width = 4 m

❖ To Verify :-

• Length × Width = Area

Now,

• ➛ Length × Width = 7 m × 4 m = 28 sq. m

Again,

• ➛ Area = 28 sq. m

$\: \: \: \: \: \bigstar \: \: \: \: \boxed{ \sf{ \large{ \therefore \: \: Length × Width = Area}}}$

• Hence Verified.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

➤ Rectangle :-

• A rectangle is a plane figure which has four sides and four angles. Each of the four angles are right angles, i.e, 90°. Again, the opposite sides of a rectangle are of equal length and parallel.

• A rectangle is or a quadrilateral which opposite sides are equal and parallel to each other and each of the four angles is a right angle.

• Area of a rectangle = Length × Width

• Perimeter of a rectangle = 2 (Length + Width)
