Question

The length of one of the sides of
a rectangle is 5 metre. If the area
of the square constructed on its
diagonal is 169 sq. cm., then what
is the perimeter of the rectangle
in metre?
(A) 36
(B) 50
(c) 34
(D) 30​

Answer 1

Step-by-step explanation:

34 will be the answer.

let the other side be x

area of square = 169

so side = 13

5² + x² = 13²

from here

x = 12

perimeter = 2[12+5]

=34
