Answer 1

Answer:

(i) required area of the banner is 9032.24 cm^2

(ii) cost of the party banner is 180644.8 rupees

Step-by-step explanation:

in the question ,

length of the banner is , l = 177.80 cm

width of the banner is , w = 50.8 cm

then area of the banner is = l × w cm^2

= (177.80×50.8) cm^2

= 9032.24 cm^2

therefore required area of the banner is 9032.24 cm^2

if per cm square cost of the banner is 20 rupees

and also total area of the banner is 9032.24 cm^2

then total cost of the banner is (9032.24×20) = 180644.8 rupees

therefore cost of the party banner is 180644.8 rupees

Answer 2

Answer:

i) Area =9032.24$cm^{2}$  ii) 180644.80 Rupees

Step-by-step explanation:

According to the information provided in the question it is given as

Length of banner =l= 177.80cm

Width of banner = w=50.8 cm

We need to find the

(i) What is the area of the party banner?

(ii) Find the cost of the party banner if the cost is Rs.20per sq.cm.

A seen in the question it is clearly indicate that the banner is in the shape of rectangle so we find the area of rectangle

$A = l\times w\\A = 177.80\times 50.8 \\A=9032.24cm^{2}$

Now we find the cost of party banner = Area of banner x rate /$cm^{2}$

Putting the value we get the answer

$Cost of banner = A \times Rate /cm^{2}$

$C =9032.24 \times 20\\C =180644.80 rupees$
