Answer 2

Answer:

• 16:- x= 20
• 17:- Perimeter= 400cm

Step-by-step explanation:

16.

$\frac{2}{5} x + 7 = 15$

$\frac{2}{5} x = 15 - 7$

$\frac{2}{5} x = 8$

$x = 8 \times \frac{5}{2} = 4 \times 5$

x= 20

17. Sides of rectangle= 1m 30cm= 130cm

Another side= 70cm

Perimeter of rectangle= 2(l+b)

= 2(130+70)

= 2× 200

= 400 cm
