Question

perimeter and area Answer??? Fast​

Answer 1

Answer:

Perimeter = 45 cm.

Area = 65 cm square.

Step-by-step explanation:

Perimeter = Sum of all sides of the given figure

=(2.5+4+2.5+4+2.5+4+2.5+0.5+10+12.5)cm

=45cm.

For finding area, divide the given figure into 4 rectangles.

Area of 1st rectangle = 2.5×4

= 10 cm square.

Area of second rectangle = (2.5+2.5)×4

= 5×4

= 20cm square.

Area of 3rd rectangle = (2.5+2.5+2.5)×4

= 7.5×4

= 30 cm square.

Area of 4th rectangle = (2.5+2.5+2.5+2.5)×0.5

= 10×0.5

= 5 cm square.

Therefore,

Area of the given figure = Area of all the 4

rectangles

= 10+20+30+5

= 65 cm square.
