Question

The diagonal and one side of a rectangular plot are 65 m and 63 m, respectively. What is the perimeter of the rectangular plot?

• A. 196 m
• B. 256 m
• C. 225 m
• D. 158 m

Answer 1

Answer:

D. 158 m

using pythagoras theorem

$diagonal^2=lenght^2+breadth^2$

$side=\sqrt{65^2-63^2}$

$side=\sqrt{4225-3969}$

$side=\sqrt{256}$

$side=16$

$perimeter=2(16+63)$

$=perimeter=158$
