Pls find the answer for the 9 question

Answer 1

perimeter of parallelogram = tu 2 area+ base

70=2{3x+4x}

70=6x+8x

70=14x

x= 70÷14=5ans

one side equals 3x equal

3 x 5= 15ans......

second side = 4x = 4 multiply 5 equal 20ans....

Pls tell me if it is right

Answer 2

Step-by-step explanation:

Let them in the form of x = 3 x : 4 x

Now , Perimeter = 70 cm

2(l+b) = 70 cm

2(3x+4x) = 70 cm

2(7x) = 70 cm

7x = 70/2

7 x = 35 cm

x = 5 cm

Now ,

3 x = 3× 5 cm = 15 cm

4 x = 4× 5 cm = 20 cm
