Answer»

Answer:

a. sides of rectangle are 30,10 cm

b. 1840m

Step-by-step explanation:

a. Perimeter of rectangle = perimeter of square =80 cm

⇒2(l+b)=45=80

⇒S=

4

80

=20 cm;2(l+b)=80

⇒l+b=40 cm - (1)

difference m areas = 100 cm

2

5

2

−(LB)=100

(20)(20)−(lb)=100

⇒lb=300 - (2)

From (1) and (2)

30+10=40;3×10=l×b

⇒l=30 and b=10

sides of rectangle are 30,10 cm

b. l=135m

b=95m

perimeter of a rectangle = 2(l+b)

'' = 2(135+95)

" =2(230)

" =460

if four TIME then distance will be 460×4=1840m
