Solution:-​

Answer 1

Answer:

500×300/50=₹3000

Step-by-step explanation:

500×300/50=₹3000

Answer 2

Given :-

Length of an advertising banner = 5 m

Breadth of an advertising banner = 3 m

The cost of making it per meter square = Rs. 50

To Find :-

The cost of making an advertising banner.

Analysis :-

Firstly, substitute the length and breadth is the formula of area and find the area accordingly.

Multiply the cost of per meter to the area in order to find the cost of making an advertising banner.

Solution :-

We know that,

• l = Length
• b = Breadth
• a = Area

By the formula,

$\underline{\boxed{\sf Area \ of \ the \ rectangle=Length \times Breadth}}$

Given that,

Length (l) = 5 m

Breadth (b) = 3 m

Substituting their values,

a = 5 × 3

a = 15 m²

Therefore, the area of the advertising banner is 15 m².

According to the question,

Cost of making an advertising banner = Cost per meter × Area

By substituting,

Cost of making an advertising banner = 50 × 15

Cost = Rs. 750

Therefore, the cost of making an advertising banner measures is Rs. 750
