Question

Find the perimeter of the following rectangle, given its area and its breadth
c) Area = 1.76 cm and breadth = 8 mm
​

Answer 1

Answer:

6 cm

Step-by-step explanation:

Area=1.76cm

breadth=8mm( breadth is in mm so we convert into cm)

breadth=8×0.1

breadth= 0.8cm

Now,

Area= L×b

1.76=L×0.8

L=1.76/0.8

L= 2.2 cm

Now we know that

Perimeter= 2(l+b)

Perimeter= 2(2.2+0.8)

Perimeter= 2×3

Perimeter = 6 cm

i hope u understand my solution

pls mark me as brainlist if u understand my solution
