Question

the area of a rectangular sheet of Aluminium is 400 CM square if the breadth of the sheet is 16 cm find its length also find the perimeter of the aluminium sheet

Answer 1

Area = (length)(breadth)
400cm² = (length)(16)
(length) = 400/16 = 25cm

Perimeter = 2(l+b)
Perimeter = 2(25+16)
Perimeter = 2(41)
Perimeter = 82cm

Answer 2

AREA OF RECTANGLE = l x b

400=l x 16

l = 400/16

l = 25cm

perimeter of rectangle = 2 (l+b)

                                     = 2(25+16)

                                     =82cm
