Answer 1

Answer:

2.34 cans of paint

Step-by-step explanation:

Length of wall = 13 feet

Width of wall = 9 feet

Area of wall = 13*9 = 117 sq. feet

Area covered by one can of paint = 50 sq. feet

So, 1 sq. feet area is covered by 1/50 cans of paint.

So, 117 sq. feet area would be covered by ---> 1*117/50 cans

=> 2.34 cans of paint.

Hope this helps.....

Answer 2

$\bigstar$ Question:

Lucy is painting one wall in her bedroom. The wall measures 13 feet long and 9 feet wide. If one can of paint covers 50 square feet, will it be enough? Justify.

$\bigstar$ Given:

• Length of the wall = 13 feet
• Width of the wall = 9 feet
• Area covered by one can of paint = 50 sq. feet

$\bigstar$ To Find:

• If one can of paint that covers 50 feet be enough to paint.

$\bigstar$ Solution:

Given,

Length of the wall = 13 feet

Width of the wall = 9 feet

Area covered by one can of paint = 50 sq. feet

$\boxed{\sf Area=Length \times Breadth}$

Now, finding the area of the wall

Area of the wall = $\sf 13 \times 9$

$\implies \sf 117 \: sq. \: feet$

Finding the cans required,

Paint cans required to paint the wall $= \sf \dfrac{Area \: of \: the \: wall}{Area \: covered \: by \: one \: can}$

$\implies \sf \dfrac{117}{50}$

$\implies \sf \underline{\underline{2.34 \: cans}}$

∴ The given amount of paint is not enough to paint the wall. 2.34 cans are required to paint the wall.

$\bigstar$ Points to Note:

➤ The formula for finding the area is Length × Breadth

➤ Area is the space present inside the flat boundary.

➤ The SI unit of area is Square metre.
