Question

26Q. The area of a rectangular sheet of paper is 20 cm2. Its length is 5 cm. 1 point
Find its width. *​

Answer 1

Answer: area of rectangle =l*b=20                                                                        now we have the the value of l=5                                                                                                          we need to find the value of b = 5*b=20                                                               b=20-5=15

Step-by-step explanation:

Answer 2

Answer:

$\red\bigstar$ The Width of the rectangular sheet of paper is 4cm.

SOLUTION

Area of the rectangular sheet of paper = 20cm².

Length(l) of the rectangular sheet of paper = 5cm.

We have to find the width(w) of the  rectangular sheet of paper .

$\boxed\boxed{{ \sf Area \: of \: a \: Rectangle = Length * Width = l * w}}$$\boxed{\sf Area \: of \: a \: Rectangle = Length * Width = l*b}$

$\implies$

20 = 5 × w

$\implies$

$\sf w = \dfrac{20}{5}$

$\implies$

Width (w) = 4cm.
