Question

the area of rectangle is 80 square cm if its length is 16cm calculate the perimeter ​

Answer 1

Answer: 192sq cm

Step-by-step explanation:

area of square=2*(80+16)                                                          

                       =2*96                                                                        

                       =192                

         

Answer 2

Area = 80 square cm
Perimeter = ?
Length = 16 cm
Breadth = ?
Area = length x breadth (b)
= 16 x b
Substitute the area
80=16 x b
b = 80/16
b = 5 cm
Perimeter = 2 (length + breadth)
= 2 (16 + 5)
= 2 x 21
= 42 cm

Therefore, perimeter is 42 cm and breadth is 5cm
