Question

The perimeter of rectangular grassy plot is 189 meter and breadth is 10.5 meter . Find the length and area of the plot.

Answer 1

Answer:

l=84 m

Area=882 m²

Step-by-step explanation:

Given:

b = 10.5 m

l = ?

Perimeter of a rectangle = 2(l+b) = 189 m

⇒l+b=94.5

⇒l+10.5=94.5

⇒l=84 m

Now,

Area of the rectangular grassy plot= l*b

⇒Area=10.5*84

⇒Area=882 m²

Answer 2

P=2(l+b)

189=2(l+10.5)

94.5=l+10.5

l=84m

area=l×b

=84×10.5

=882metersquare
