Question

find the area and perimeter of the following rectilinear shape​

Answer 1

Step-by-step explanation:

Area of rectangle = length x breadth

Perimeter of rectangle = 2[length + breadth]

length of rectangle = l

breadth of rectangle = b

NOTE :

ALL MEASUREMENTS ARE GIVEN IN PICTURE WHICH IS POSTED

There are 3 rectangles in the figure

First Rectangle :

Area = 18 x 10 = 180 --------(1)

Perimeter = 2[18+10]=2[28]=56 ---------(2)

Second Rectangle :

Area = 14 x 5 = 70 -------(3)

Perimeter = 2[14+5] = 2[19] = 38 ---------(4)

Third Rectangle (or) Square :

Area = 10 x 10 = 100 --------(5)

Perimeter = 4(10)=40. { in case of square }

or

2[10+10]=2[20]=40 { in case of rectangle }

Perimeter = 40 --------(6)

TOTAL FIGURE :

Area = (1)+(3)+(5)

= 180+70+100

= 350

Perimeter = (2)+(4)+(6)

= 56+38+40
