Find the area and the perimeter of the figure
below. The unit of length is centimetres.
Answers
Answer: Area = 270 units Perimeter = 114 units
Step-by-step explanation: Firstly The area of a parallelogram is Base x Height
Base of first parallelogram = 7 units
Base of first parallelogram = 15 units
Area of first Parallelogram = B x H
=7 x 15
= 105 units
Respectively
Area of second parallelogram = B x H
= 10 x 10
= 100 UNITS
Respectively
Area of Third parallelogram = B x H
= 13 x 5
= 65 UNITS
Total Area = 105 + 100 + 65
= 270 units
---------------------------------------------------------------------------
Perimeter of 1st parallelogram = 2 ( a + b)
= 2(18 + 7)
= 2 x 25
= 50 units
Perimeter of 2nd parallelogram = 2 ( a + b)
= 2(12 + 10)
= 2 x 22
= 44 units
Perimeter of 3rd parallelogram = 2 ( a + b)
= 2(6 + 13)
= 2 x 19
= 38 units
Total area = perimeter of 1st + 2nd + 3rd - ( extra perimetre)
= 50 + 44 + 38 - ( 12 + 6 )
= 132 - 18
= 114 units
