Sagot :
Answer:
Perimeter of the new box is 30.4 cm
Area of the new box is 57.76 cm²
Step-by-step explanation:
Jordan made a wooden square box, all sides of the wooden box are 6cm. If he wants to increase the length of all sides by 1.6, what will be perimeter and area of the new box?
From the question; all the side of the wooden box is 6 cm, if she increases all side by 1.6, then the sides become; 6 cm + 1.6 cm = 7.6 cm
Since all the sides are 7.6 cm, then perimeter = L + L + L + L
=7.6cm +7.6cm +7.6cm+7.6cm
=30.4cm
or
perimeter of a square = 4L
= 4 × 7.6cm
= 30.4 cm
Therefore the perimeter of the new box is 30.4 cm
To find the area;
l = 7.6 cm
Area of a square = l × l
= 7.6 cm × 7.6 cm
=57.76 cm²
Therefore area of the new box is 57.76 cm²
