Answer 1

Answer:

C ) 10cm , 7cm

Step-by-step explanation:

Its that because THe length is 3 more than the breath and the perimeter is 34 cm,

A rectangle has its opposite sides equal so 10 x 2 + 7 x 2 = 20 + 14 = 34

Hope this helps ;)

Answer 2

breadth= b

length = b+3

perimeter = 34

perimeter = 2(l+b) = 34

2(b+b+3) = 34

2(2b+3) = 34

2b+3= 17

2b = 17-3

2b = 14

b= 7cm

l= b+3 = 10 cm

c) is the correct answer.
