Question

The perimeter of a rectangle is 32 cm and its length is 10 cm. Find its breadth and area.​

Answer 1

GIVEN:-

• perimeter of rectangle = 32 cm
• length = 10 cm

TO FIND :-

• breadth = ?
• area = ?

SOLUTION:-

perimeter of a rectangle = 2(l+b)

                                    32 =  2(10+b)

                                   32   =  20 + 2b

                                    2b  =   20-32

                                    2b  = 12

                                     b   = 12/2

                                     b =  6cm

hence, breadth is 6cm

now, area of a rectangle = l × b

                                         = 10 × 6

                                         = 60cm

therefore, are of a rectangle is 60 cm .
