Question

2. If the area of a rectangle is 70 cm2 and its breadth is 5 cm, find its length.

Answer 1

$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

• area = 70 cm²
• breadth = 5cm

we know that,

• area of rectangle = length × breadth

➪ 70 = length × 5

➪ length = 70/5

➪ length = 14 cm

so, length of the rectangle is 14cm

Answer 2

★$\large\mathfrak \pink{Solution:-}$

★$\underline \mathbb{GIVEN:-}$

$Area = 70 \: {cm}^{2}$

$Breadth \: = 5 \: cm$

$\underline \mathbb{TO \: FIND:-}$

The Length of the rectangle.

★$\underline \mathbb{FORMULA:-}$

$\fbox{Length × Breadth = Area}$

★$\underline \mathbb{BY \: THE \: PROBLEM:-}$

$Length × Breadth = Area\\ \\ \implies \: Length \times 5 = 70 \\ \\ \implies \: \: Length = \frac{70}{5} \\ \\\implies \:Length = 14 \: cm$

★$\underline \mathbb{ANSWER:-}$

$\implies ★ \fbox{\:Length = 14 \: cm}$

★$\underline \mathbb{ADDITIONAL\: INFORMATION:-}$

★ $Perimeter \implies 2 \times (length + breadth)$

★$Diagonal \implies \sqrt{ {(length)}^{2} + {(breadth)}^{2} \: }$
