Question

In Is 5 m, find the area
6. A wooden sheet is 15 m long and 6 m broad. It has to b
sides. Find the cost of painting at 30 per square metre.
​

Answer 1

$\huge\mathbb{SOLUTION:-}$

$\sf\underline{\blue{Given:-}}$

• the sides of woorden sheet

length=15m

Breadth=66m

we have to find the Area

Now

$\boxed{\sf{Area\:of\: rectangle=length\times breadth}}$

So Area of sheet

$\sf:\implies Area=l\times b\\ \\ \sf:\implies Area=15\times 6\\ \\ \sf:\implies Area=90m{}^{2}$

Area of sheet is 90sq.m

Now the cost of painting

$\sf\implies cost\:of\: 1m{}^{2}=30Rs\\ \\ \sf:\implies Cost\:of\:90m{}^{2}=30\times 90\\ \\ \sf:\implies Cost\:of\: painting=2700Rs$

$\boxed{\sf{\red{Cost\: of\: painting=2700Rs.}}}$

Answer 2

Answer:

2700

Step-by-step explanation:

Given :

Length and breadth of wooden sheet 15 m and 6 m respectively.

Now :

Area of wooden sheet = 15 × 6 m²

Area of wooden sheet = 90 m² .

For 1 m² cost is Rs 30

For 90 m² = 90 × 30

Total cost =  Rs 2700

Hence we get answer.
