20 m. Find its area.
​

Answer 1

Answer

The area of rectangle = Length×Diagonal

= (16×20)m

= 320m. Answer

Answer 2

192 sq.m

Step-by-step explanation:

Given.

diagonal =20m

length =16m

breadth =?

by pythagoras thm

H^2=(side 1)^2+(side2)^2

(20)^2=ab^2 +16^2

400=ab^2+ 256

400- 256=ab^2

144 =ab^2

ab=under root 144

ab=12

:.Breadth =12m

area of rectangle =l×b

:.12×16

=192sq.m
