Question

The perimeter of rectangle whos one side is
20m. the diagonal is 29 m
measures

​

Answer 1

Answer:

length of rectangle = 20 m

diagonal of rectangle = 29 m

by using Pythagoras formula ,

( H ) ^2 = ( P ) ^2 + ( B )^2

(29 ) ^2 = (x ) ^2 + ( 20 ) ^2

841 = x ^2 + 400

841 - 400 = x ^2

441 = x ^2

x = 21 m

so , breadth of rectangle = 21 m

perimeter of rectangle = 2 ( l + b )

= 2 ( 20 +21 )

= 2 ( 41 )

= 82 m

Answer 2

answer is 82 m...........
