Question

The area of rectangular sheet is 500 square cm. If the length of the sheet is 10 cm, what is its breadth. If the cost of painting the sheet is rupees 23 per square cm, what
amount would be spent to paint 3 such sheets?

Answer 1

Lets find the breadth :

• l × b = area of rectangle

• 10 × b = 500 cm²

• b = $\dfrac{50 \cancel0}{{1\cancel0}}$= 50 cm

the cost of painting 1 sheet is 23 rs

• the cost of 3 sheets are :

• 3 × 23 = 69 rs

Final answer:

${\therefore \sf{\:The \: cost \: of \: painting \: 3 \: sheets \: is \: 69 \: rs.}}$

$\sf{\therefore\:A\: sheet\:breadth \: is \: 50 \: cm.}$
