Question

the area of a rectangle sheet is 500 cm. if the length of the sheet is 25cm , what is its width? also find the perimeter of the rectangular sheet

Answer 1

Area of Rectangle= l×b
length= 25cm
area=500 cm^2

500=25×b
500/25=b
b=20 cm

Perimeter of Rectangle= 2(l+b)

= 2(25+20)
2×45= 90 cm.

May it help...

Answer 2

Width = 20cm

Perimeter of the rectangular sheet = 90cm

The whole distance covered by a rectangle's edges or sides is known as its perimeter. Because a rectangle has four sides, the perimeter of the rectangle is equal to the sum of the four sides. It is a linear measure.

Given:

Area of a rectangle sheet = 500$cm^{2}$

Length of the sheet = 25cm

To find:

Width, perimeter

Area of a rectangle  = length*breadth

                         500 = 25*b

                              b = $\frac{500}{25}$

                              b = 20cm

Perimeter of the rectangle = 2(length+breadth)    

                                            = 2(25+20)

                                            = 2(45)

                                            = 90cm
