Question

find the area and perimeter of the given figure please tell step by step please I will give you 50 point and right answer mark as brainlest answer ​

Answer 1

THE GARDEN CAN BE DIVIDED INTO 1 RECTANGLE AND 2 SEMI CIRCLES.

NOW,radius of semi circle= r = 5/2 =2.5m

ALSO,length of rectangle= 30 ‐ 2.5 ‐ 2.5

= 30 ‐(2.5+2.5)

= 30 ‐ 5

= 25m

AND, breadth of rectangle = 5m

AREA OF 2 SEMI CIRCLES:–

πr²

22/7 × 5/2 × 5/2

=39.28m²

AREA OF RECTANGLE:–

L × B

25 × 5

=125m²

THUS, AREA OF GARDEN.

AREA OF RECTANGLE+AREA OF SEMI CIRCLES

39.28+125

=164.28m²

NOW, perimeter of garden.

(2 × 22/7 × 5/2)+(2×25)

=110/7 + 50

=65.71 m

THEREFORE,

AREA=164.28m²

PERIMETER=65.71 m
