Question

Find the Perimeter of a rectangle whose length is 7 cm and breadth is 4 cm. ​

Answer 1

Given :—

Length $\longmapsto\tt\bf$ 7cm .

Breath $\longmapsto\tt\bf$ 4cm .

To Find :—

Perimeter of The Rectangle .

Formula Used :—

$\longmapsto\tt\bf$2 ( l + b ) .

Solution :—

Put The Values in the Formula .

$\longrightarrow2( \: 7 \: + \: 4) \\ \\ \longrightarrow2(11) \\ \\\longrightarrow 22cm {}^{2}$

Answer 2

Given :-

• Length = 7 cm
• Breadth = 4 cm

To Find :-

• Perimeter of the rectangle.

Solution :-

We know that,

Perimeter of a rectangle = 2 (l + b)

→ 2 × (7 + 4)

→ 2 × 11

→ 22 cm²

Therefore, Perimeter of the rectangle = 22 cm²
