Question

the perimeter of a rectangular grassy plot is 189 m and its breadth is 10.5 m . find the length and area of the plot

Answer 1

Answer:

length = 178.5

Area = Area = 1874.2

Step-by-step explanation:

Perimeter = Length + Breadth

Length = Perimeter - Breadth = 178.5m

Area = Length x Breadth

= 178.5 x 10.5

= 1874.2

Answer 2

Answer:

length= 84 m

area= 882m^2

Step-by-step explanation:

let length of the rectangular plot be "l"

Perimeter of rectangle= 2 (l+b)

189 = 2 (l+10.5)

l+10.5 = 189÷2

l = 94.5 - 10.5

l = 84 m

AREA OF RECTANGULAR PLOT = l×b

= 84×10.5

= 882 m^2
