Question

12. From the given figure, find the perimeter of:
(a) the triangle ABE
(b) the rectangle BCDE
Whose perimeter is greater-triangle or rectangle?
​

Answer 1

Answer:

(a) 5.05

(b) 7.16

the greater perimeter is rectangle

Step-by-step explanation:

Perimeter of the triangle =sum of all side

= 3/2+11/4+4/5

=5.05 answer

perimeter of the rectangle =2 (L+B)

= 2 (5/6 + 11/4)

= 7.16 answer

Answer 2

Answer:

Step-by-step explanation:

A) Perimeterof ABE = AB+BE+AE

= 3/2 + 2 3/4 + 4/5

= 3/2 + 11/4 + 4/5

= [(3*10) + (11*5) +( 4*4) ]/20

= (30+55+16)/20

=101/20

B) In rectangle BCDE

Perimeter = BC+CD+DE+EB
