Answer 1

S O L U T I O N

ANSWER ⤵️

Perimeter = 142.2 m

E X P L A N A T I O N

GIVEN ⤵️

▪Length = 0.1 m

▪Area = 7.1 m²

TO FIND ⤵️

• Perimeter of rectangle

USING THE FORMULAS ⤵️

• Area = Width (Breadth) × Length

• Perimeter = 2 × (Length + Width)

ABBREVIATIONS USED HERE ⤵️

• Area = A

• Length = L / l

• Perimeter = P / p

• Metre = m

SOLVING FOR PERIMETER ⤵️

$Perimeter (p)\: \\ \\ = 2 \: l + 2 \frac{A}{l} \\ = 2 \: • \: 0.1 + 2 \: • \: \frac{7.1}{0.1} \\ = 142.2 \: m$
