Solution :-
1) Perimerer of the Whole Figure
Refer image*
For different blocks as stated.
Perimeter of =
= 15 + 11 + 26 + 10 + 15 + 11
= 88 m
Area of "1st block" = 15 × 16 = 240
Area of 2nd block = 11 × 10 = 110
Area of "3rd block = 10×15 = 150
Area of Whole plot of land = 150 + 110 + 240 =
Formulas used :-
Area of rectangle = length × breadth
= 500 m²
It is already given that all
angles are of 90°.......
So... we can say that ......
ABMF is a rectangle and
MCDE is also a rectangle.....
Finding all side of the adjoining plot...
BC = 15m + 11m [ as shown in fig.]
»» BC = 26m.
EF = 26m - 10m [ as shown in fig.]
»» EF = 16m.
Perimeter of the adjoining plot
P = Sum of all sides
»» P = AB + BC + CD + DE + EF + FA
»» P = ( 26 + 26 + 10 + 11 + 16 + 15 )m.
»» P = 104m.
Perimeter = 104m.
Area of the adjoining plot
Area of ABMF = Lenth ×Breadth
Here.... lenght = 26m and breadth = 15m.
»» Area = 26m × 15m
»» Area = 390m²
Area of MCDE = Lenth ×Breadth
Here.... lenght = 11m and breadth = 10m.
»» Area = 11m × 10m
»» Area = 110m²
Area of adjoining plot = Area of ABMF + Area of MCDE
Area of adjoining plot = 390m² + 110m²
»» 500m²
