Question

what is the area of a rectangular plot whose one side is 8m long and diagonal is of length 17m.​

Answer 1

AREA OF RECTANGLE=

(LENGTH× BREADTH)

AREA= 8×17

=136m²

Answer 2

Answer:

Given:-

One side=8m

Let's assume the side as the breath

Diagonal=17m

According to Pythagoras Theoram:-

${d}^{2} = {l}^{2} + {b}^{2}$

${(17m)}^{2} = {l}^{2} + {(8m) }^{2}$

$289 {m}^{2} = {l}^{2} + {64m}^{2}$

${l}^{2} = {289m}^{2} - {64m}^{2}$

${l}^{2} = 225 {m}^{2}$

$l = \sqrt{225 {m}^{2} }$

$l = 15m$

b=8m

Now,

Since

Area of rectangular plot=l×b

=15m×8m

$= 120 {m}^{2}$
