Question

complete the following table ,breadth 9.5 perimeter 49 cm find length and area

Answer 1

Answer:

15, 142.5 cm^{2}

Step-by-step explanation:

2(l+b) = Perimeter

2 x ( l + 9.5) = 49

∴l = 49/2 - 9.5 = 15

∴ l = 15 cm

Area = l x b = 15 x 9.5 = 142.5 cm^{2}

Answer 2

The length is 15 cm and the area is 142.5 sq.cm.

Step-by-step explanation:

Perimeter of rectangle = 2(Length +Breadth)

Breadth = 9.5 cm

Perimeter = 49 cm

So, 49 =2(Length +9.5)

$\frac{49}{2}-9.5=Length$

15 = Length

Area of rectangle =$length \times Breadth$

Area of rectangle = $15 \times 9.5 = 142.5 cm^2$

Hence The length is 15 cm and the area is 142.5 sq.cm.
