​

Answer 1

Answer:

3.4 m , 0.6m²

Step-by-step explanation:

L = 1.2m = 120cm

b = 50 cm

Length of frame= perimeter= 2(l+b)

= 2( 170)

=340 cm

= 3.4 m

area of glass = area = lb

= 120×50

= 6000cm²

=0.6m²

if it is correct give me a friend request please

Answer 2

hope this helps...

also instead of converting the breadth into m, you can also convert the l into cm. it'll be easier.
