Question

the area of a rectangle is 540 CM square and its length is 36 cm find its width
and perimeter

Answer 1

Length(l) = 36 cm

Breadth(b) = b

Area = 540 cm^2

Area= l*b

So, b=area/l

        = 540/36

        = 15 cm

Breadth = 15 cm

Perimeter = 2(l+b)

                = 2(36+15)

                = 2*51

               = 102 cm

(Ans): Breadth = 15 cm; Perimeter = 102 cm.
