Question

 Find the perimeter of a rectangle whose one side measures 20 m and the diagonal are 29 m.
​

Answer 1

Step-by-step explanation:

perimeter of rectangle=2(l+b). [l=30m]

(b)^2 = (29)^2-(20)^2

= (b)^2 = 841-400

= (b)^2 =441

= (b) = √441

=. (b). =. 21

perimeter of rectangle= 2(l+b)

= 2(20+21)

= 2x 41

= 82 m Ans.
