Question

5. The area of a rectangle is 102 cm². If its length is 17 cm, what is its perimeter.
​

Answer 1

Answer:

let b be the breadth

Area of rectangle = 102

b = 102

b = 102/17

b = 6

Perimeter of rectangle = 2 ( l+b)

=> 2*( 17 + 6)

=> 2×23

=> 46 cm

Answer 2

Answer:

perimeter=46cm

Explanation:

l x b= 102

b=102/17

b=6

now, perimeter=2(l+b)

=2(6+17)

= 46
