Question

seorang tukang kayu akan memotong tripleks berukuran 3,5 meter x 3,5 meter. tentukan luas dan keliling tripleks tersebut​

Answer 1

Answer:

Part 1) $A=12.25\ m^2$

Part 2) $P=14\ m$

Step-by-step explanation:

The question in English is

A carpenter will cut plywood measuring 3.5 meters x 3.5 meters. Determine the area and perimeter of the plywood.

Part 1) Determine the area

we know that

The area of a square is given by the formula

$A=b^2$

where

b is the length side

we have

$b=3.5\ m$

substitute

$A=3.5^2=12.25\ m^2$

Part 2) Determine the perimeter

we know that

The perimeter of a square is given by the formula

$P=4b$

where

b is the length side

we have

$b=3.5\ m$

substitute

$P=4(3.5)=14\ m$
