Question

14. The perimeter of a rectangular grassy plot is
189 m and breadth is 10,5 m. Find the length and area of the plot
and area of the plot
​

Answer 1

Answer:

Perimeter = 189m

Breadth = 10.5m

Perimeter = 2(l+b)

189 = 2(l+10.5)

189 = 2l + 21

189-21 = 2l

168 = 2l

168/2 = l

84 metre = length

Area = l x b

Area = 10.5 x 84

Area = 882 metre

Answer 2

Given , Perimeter rectangular grassy plot=189m

Breadth=10.5m

Length=?2(X+10.5)=189

X+10.5=189/2=94.5

X=94.4–10.5=83.9

Length=83.9m

Area of rectangular grassyplot=l×b =83.9×10.5=880.95

Therefore,Area of rectangular grassy plot=880.95m²
