58cm
4/7 cm
142 cm
D
None of these​

Answer 1

Step-by-step explanation:

Given If AB =BC =CD then, find perimeter of adjoining figure.

We need to find the perimeter of the given adjoining figure.

• Now from the given figure AB = 7m and CD = 7 m. So join BC
• So we have two arcs AC and BD
• So Arc AC + Arc BD + AB + CD.
• (Now circumference of the circle is 2πr
• So ½ the circle will be πr)
• So π x 7 + π x 7 + 7 + 7
•           14 π + 14
•          14 x 22/7 + 14
•           2 x 22 + 14
•            44 + 14
•               58 m
• Therefore the perimeter of the adjoining figure is 58 m

Answer 2

Answer:

so

14×22/7+14

(the circumference of circle is 2×22/7×radius)

2×22+14

44+14

perimeter of adjoining figure is 58m
